Ephemeral PostgreSQL

Run tests on an isolated, temporary PostgreSQL database.

Temporary database created with pg_tmp have a limited shared memory footprint and are automatically garbage-collected after the number of seconds specified by the -w option (the default is 60).

pg_tmp reduces the wait time for a new database to less than one second by initializing a database in the background that is used by subsequent invocations.

Source Installation - BSD, Mac OS, and Linux

make install

Or to specify a specific installation location

PREFIX=$HOME/local make install

Source Installation - Solaris

LDFLAGS='-lsocket -lnsl' make install
