ECPG is the standard, in the PostgreSQL database built-in, client programming interface for embedding SQL in programs written in the C programming language. [1] It provides the option for accessing the PostgreSQL database directly from the C code in the application, using SQL commands.
PostgreSQL includes built-in support for regular B-tree and hash table indexes, and four index access methods: generalized search trees , generalized inverted indexes (GIN), Space-Partitioned GiST (SP-GiST) [42] and Block Range Indexes (BRIN). In addition, user-defined index methods can be created, although this is quite an involved process.
A pool of database connections can be created and then shared among the applications that need to access the database. The connection object obtained from the connection pool is often a wrapper around the actual database connection. The wrapper understands its relationship with the pool, and hides the details of the pool from the application.

By the next decade, PostgreSQL had become a commercially viable database, and is the basis for several current products that maintain its ORDBMS features. Computer scientists came to refer to these products as "object–relational database management systems" or ORDBMSs.
A relational database (RDB [1]) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. [ 2 ] A database management system used to maintain relational databases is a relational database management system ( RDBMS ).
