Why use PostgreSQL?
PostgreSQL comes with many features aimed to help developers build applications, administrators to protect data integrity and build fault-tolerant environments, and help you manage your data no matter how big or small the dataset. In addition to being free and open source, PostgreSQL is highly extensible. For example, you can define your own data types, build out custom functions, even write code from different programming languages without recompiling your database!
PostgreSQL tries to conform with the SQL standard where such conformance does not contradict traditional features or could lead to poor architectural decisions. Many of the features required by the SQL standard are supported, though sometimes with slightly differing syntax or function. Further moves towards conformance can be expected over time. As of the version 13 release in September 2020, PostgreSQL conforms to at least 170 of the 179 mandatory features for SQL:2016 Core conformance. As of this writing, no relational database meets full conformance with this standard.
Below is an inexhaustive list of various features found in PostgreSQL, with more being added in every major release:
Data Types
Primitives: Integer, Numeric, String, Boolean
Structured: Date/Time, Array, Range, UUID
Document: JSON/JSONB, XML, Key-value (Hstore)
Geometry: Point, Line, Circle, Polygon
Customizations: Composite, Custom Types
Data Integrity
UNIQUE, NOT NULL
Primary Keys
Foreign Keys
Exclusion Constraints
Explicit Locks, Advisory Locks
Concurrency, Performance
Indexing: B-tree, Multicolumn, Expressions, Partial
Advanced Indexing: GiST, SP-Gist, KNN Gist, GIN, BRIN, Covering indexes, Bloom filters
Sophisticated query planner / optimizer, index-only scans, multicolumn statistics
Transactions, Nested Transactions (via savepoints)
Multi-Version concurrency Control (MVCC)
Parallelization of read queries and building B-tree indexes
Table partitioning
All transaction isolation levels defined in the SQL standard, including Serializable
Just-in-time (JIT) compilation of expressions
Reliability, Disaster Recovery
Write-ahead Logging (WAL)
Replication: Asynchronous, Synchronous, Logical
Point-in-time-recovery (PITR), active standbys
Tablespaces
Security
Authentication: GSSAPI, SSPI, LDAP, SCRAM-SHA-256, Certificate, and more
Robust access-control system
Column and row-level security
Multi-factor authentication with certificates and an additional method
Extensibility
Stored functions and procedures
Procedural Languages: PL/PGSQL, Perl, Python (and many more)
SQL/JSON path expressions
Foreign data wrappers: connect to other databases or streams with a standard SQL interface
Customizable storage interface for tables
Many extensions that provide additional functionality, including PostGIS
Internationalisation, Text Search
Support for international character sets, e.g. through ICU collations
Case-insensitive and accent-insensitive collations
Full-text search

PostgreSQL is highly scalable both in terms of the sheer amount of data it can manage and the number of concurrent users it can serve. Production environments have active PostgreSQL clusters that manage many terabytes of data, and dedicated systems that manage petabytes.

Looking for Programming assignment help? There are so many players in the market who claim to provide Programming assignment help but there are only few who you can really trust upon. We come across so many experts who claim to carry years of experience in providing C assignment help or C++ Assignment Help, they also claim to be Java Assignment Help experts, at some places they advertise to be Python Assignment Help experts too. Basically they project as if they are the best Computer science assignment help provider available. But what really strikes me is how can somebody master so many programming languages and provide homework help for all!
My experience says if you are in need to hire an expert you should definitely check online reviews. Spend some time going through the reviews, that will give you an idea about the genuinity of the expert. There are many educational websites that provide experts for almost all the subjects. You can ask them for a Statistics homework help expert if you are stuck with topics like SPSS, SAS, STATA or others. There are few good websites that can provide you with a decent Statistics assignment help expert at reasonable cost.
I myself have seeked Matlab Assignment Help and Economics assignment help from these websites. The Economics homework help tutor I hired in my first semester stayed with me till I Graduated although I had to take the services of Matlab homework help expert only twice. Although I had to hire new experts every semester and this was quite understandable as not all not all experts can provide Math homework help on all topics.
In short, what I want to share with you is that there are so many experts and sites available to provide you with homework help, but you need to choose wisely.

I am a student at a renowned university in California. Earlyon i was very excited and had a sense of pride in me being a student of the university. I was always good in academics and gained good grades. Even today I am sincere and honest with my studies. But what I saw by the end of 1st semester was absolutely demotivating for me. I saw that my mates hired professional help to get their assignments done. Fellows who were barely attentive in class were all submitting assignments exactly as required. I was very sad and wanted to report it to the faculties but I hesitated. The work submitted by everyone was original and everyone gained good grades. I really started thinking, is it worth the pain to study so much when I could hire experts to do the task for me. But with time I realised that there is no alternative to knowledge and it can only be gained by studying. Today I have stopped noticing what others do, I just focus on me and my studies.
One day I was sitting with a classmate of mine and I asked him how he managed to get expert help. He walked me through the entire process and I was just stunned to see how easy it is to score an A in all the assignments without studying. There are industry accepted keywords to find professional help. Everything was so organized and simple. I really felt sorry thinking where the education system was going. All he had to do was to google the following to find experts:-
Looking for Programming assignment help
C assignment help Tutor
Online C++ Assignment Help expert
Need Java Assignment Help
Do you provide Python Assignment Help

I am an experienced programmer and I have been tutoring students online for the past 10 years. As a professional I expertise in C++ but I have been providing assistance to students in almost all object oriented and low level programming languages.
Students approach me to get their assignments done but i believe in imparting knowledge so I guide them with the process and clear their doubts instead of providing them assignments. I have been approached by so many students over the years and they approach me saying I am Looking for Programming assignment help, Are you a C assignment help Tutor, Online C++ Assignment Help expert needed, Need Java Assignment Help, Do you provide Python Assignment Help? Need Computer science assignment help and so many other ways.But my way of working is simple. I will not do your assignments in lieu of money. I will guide you through the process, i will clear your doubts but i will not do your work.
Recently I have realised that students not only from programming backgrounds but from all domains have started contacting me. They ask me questions like Are you a Math homework help expert or a Math assignment help expert, Statistics homework help expert needed, Statistics assignment help expert needed, Looking for Matlab homework help or Matlab Assignment Help, Online Economics homework help required, Online Economics assignment help required and so on.It is quite shocking for me how students look for shortcuts these days to gain good grades.

This is the first time I have asked for the change of a Matlab homework help tutor. Having worked with you for over three years I have never had a problem working with you. However last week I hired a tutor for Matlab Assignment Help for an image processing paper. He was not providing updates of the work 4 days after he started. I just got tired and requested a change which was done immediately. I am happy to report that my work is now progressing well with the updates I wanted.

I had a funny experience with your Matlab Assignment Help experts that I wouldn’t know how to describe. You did my image processing assignment sometime back and I sent it to our professor. I scored 31/50 and thought it was a terrible score. However, I wondered why my professor had indicated that I had performed excellently. After following up I found that I scored the highest. 31 seemed a joke to me but no one went past that. Initially, I thought you guys had failed me but it turns out that your Matlab homework help experts did excellent work. Thank you. I will hire you again soon

I have been told that you guys are excellent Matlab Assignment Help experts. How long does it take to complete a communications system project? I have seen your email address and I will be sending my details for your perusal. If your Matlab homework help tutors are in a position to do it which is my final year project please let me know how much time you need.
