psql's already implemented HISTCONTROL and HISTSIZE variables, and

This variable contains the filename used to save the history.
Its default value is <filename>~/.psql_history</filename>.
For example, use:
<programlisting>
\set HISTFILE ~/.psql_history-:DBNAME
</programlisting>
in your <filename>~/.psqlrc</filename> will get psql to
maintain a separate history for each database.
