I install it on a per-user basis:

  % ls ~/libexec/zsh/_pgsql_utils
  /home/dom/libexec/zsh/_pgsql_utils

Then I've got this in my ~/.zshrc:

  fpath=( ~/libexec/zsh $fpath );

Note that it has to come before you call compinit.

It does work well for me here, under Debian and FreeBSD.  But if it's
not working correctly, I'll gladly do what I can to make it work for
you.

A quick way to check whether or not it's working is to press ^Xh after
typing in "psql ".  You should get output like this:

    % psql
    tags in context :completion::complete:psql::
        argument-1 options  (_arguments _psql _pgsql_utils)
