postgresql-client-common - 248pureos1 main

The postgresql-client-common package provides a structure under which
multiple versions of PostgreSQL client programs may be installed at
the same time. It provides a wrapper which selects the right version
for the particular cluster you want to access (with a command line
option, an environment variable, /etc/postgresql-common/user_clusters,
or ~/.postgresqlrc).

PostgreSQL is a fully featured object-relational database management
system. It supports a large part of the SQL standard and is designed
to be extensible by users in many aspects. Its features include ACID
transactions, foreign keys, views, sequences, subqueries, triggers,
outer joins, multiversion concurrency control, and user-defined types
and functions.
