The Postgres query language is a variant of the SQL3 draft
next-generation standard. It has many extensions such as an
extensible type system, inheritance, functions and production
rules. These are features carried over from the original Postgres
query language, PostQuel. This section provides an overview of how
to use Postgres SQL to perform simple operations. This manual is
only intended to give you an idea of our flavor of SQL and is in no
way a complete tutorial on SQL. Numerous books have been written on
SQL, including [MELT93] and [DATE97]. You should be aware that some
language features are not part of the ANSI standard.
