PostgreSQL Introduction

PostgreSQL is an open-source, powerful object-relational type of database system. It extends and uses the languages of SQL that consisted of various aspects that safely scale and store sophisticated data workloads. PostgreSQL's origins back to date 1986 at the California University at Berkeley as the POSTGRES project.

PostgreSQL has made a solid reputation for the reliability, architecture, data integrity, extensibility, robust aspect set, and open source community's dedication. PostgreSQL delivers innovative and performant solutions consistently. It executes on every operating system. Also, it is ACID-complaint from 2001. PostgreSQL has strong add-ons like the popular geospatial database extender, i.e., PostGIS. It has become an open source type of relational database for various organizations and people.

PostgreSQL Usage

It comes with several aspects aimed to support administrators for protecting integrity of data, developers for building applications and build an environment, i.e., fault tolerance. It also supports us for managing our data. Besides of being open and free source, it is a highly extensible database.

For example, we can define our data types, made custom functions, and write code through programming languages of different types without recompiling our database.

The following are some essential aspects detected in PostgreSQL, these aspects are included in all the major release. This list is as follows:

  • Data Integrity
    • NOT FULL, UNIQUE
    • Foreign Keys
    • Primary Keys
    • Advisory Locks, Explicit Locks
    • Exclusion Constraints
  • Data Types
    • Structured: UUID, Range, Array, Date/Time
    • Primitives: Boolean, String, Numeric, Integer
    • Document: Key-value (Hstrore), XML, JSON/JSONB
    • Geometry: Polygon, Circle, Line, Point
    • Customizations: Custom Types, Composite
  • Performance, Concurrency
    • Advanced Indexing: Bloom filters, Covering Indexes, BRIN, GIN, KNN Gist, SP-Gist, Gist
    • Indexing: Partial, Expressions, Multicolumn
    • Multicolumn statistics, Index-only scans, Sophisticated query optimizer/planner
    • Nested Transactions, Transactions
    • MVCC (Multi-Version concurrency Control)
    • Making B-tress indexes, Read query's parallelization
    • Table partitioning
    • Every transaction separation levels specified inside the SQL standard, adding Serialization
    • JIT (Just-In-Time) expression's compilation
  • Disaster Recovery, Reliability
    • Replication: Logical, Synchronous, Asynchronous
    • WAL (Write-ahead Logging)
    • Active standbys, PITR (Point-in-time recovery)
    • Tablespaces
  • Security
    • Authentication: Certificate, SCRAM-SHA-256, LDAP, SSPI, GSSAPI, and other
    • Row-column level security
    • Strong access-control system
    • Multi-factor authentication along with the certificates and additional method
  • Extensibility
    • Stored procedures and functions
    • Procedural Languages: Python, Perl, PL/PGSQL (and many others)
    • JSON/SQL path expressions
    • Justifiable Storage interface for many tables
    • Several extensions that facilitate additional functionality, and PostGIS
  • Text Search, Internationalization
    • Support for many sets of international character, e.g. by ICU collations
    • Full-text search
    • Accent-insensitive and Case-insensitive collations

5. Choosing where to save data (Data Directory's location)

We will have to choose a location for our Data Directory of Postgres cluster. Choose a right location and press "Next":

6. The superuser password settings

We will have to facilitate Postgres Unix superuser password which will be made at the installation time. So, facilitate a right password and press "Next":

7. Post number selection

We will have to choose a port number over which the server of the PostgreSQL will listen to incoming connections. Hence, facilitate a right port number. 5432 is the default port number.
