SOUNDEX call

Hi all,
I'm developing Joomla's PostgreSQL database driver that (I hope) will
be included soon in this CMS [1] [2].
During my developing time I've found a big problem, not yet resolved,
about SOUNDEX function, adopted for recent added code.
I know that SOUNDEX is present inside contrib module, but to be
installed is required database's admin privilege to be run and,
usually during a CMS installation on a remote shared server, this
privilege is not given.
Now the problem is, how can I enable SOUNDEX inside database ? Is
there a way to use it without running contrib files ?
Can I hope on SOUNDEX inclusion inside core for next release, as is
for other major databases ?

Thank you for your job!
