PostgreSQL Installation

PostgreSQL is an object-relational database management system (ORDBMS) based on POSTGRES, Version 4.2, developed at the University of California at Berkeley Computer Science Department. POSTGRES pioneered many concepts that only became available in some commercial database systems much later.
 PostgreSQL is an open-source descendant of this original Berkeley code. It supports a large part of the SQL standard and offers many modern features:
 
• complex queries
 • foreign keys
 • triggers
 • updatable views
 • transactional integrity
 • multiversion concurrency control
 Also, PostgreSQL can be extended by the user in many ways, for example by adding new
 • data types
 • functions
 • operators
 • aggregate functions
 • index methods
 • procedural languages

 And because of the liberal license, PostgreSQL can be used, modified, and distributed by anyone free of charge for any purpose, be it private, commercial, or academic.

WARNING: enabling "trust" authentication for local connections
 You can change this by editing pg_hba.conf or using the option -A, or
 --auth-local and --auth-host, the next time you run initdb.

A. Success. You can now start the database server using:

/usr/local/pgsql/bin/postgres -D /usr/local/pgsql/postgresdb/
 or
 /usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/postgresdb/ -l logfile start
