Both the system-wide <filename>psqlrc</filename> file and the user's

<filename>~/.psqlrc</filename> file can be made version-specific

by appending a dash and the <productname>PostgreSQL</productname>

release number, for example <filename>~/.psqlrc-&version;</filename>.

A matching version-specific file will be read in preference to a

major or minor release number, for example

<filename>~/.psqlrc-9.2</filename> or

<filename>~/.psqlrc-9.2.5</filename>. The most specific

version-matching file will be read in preference to a

non-version-specific file.
