The incantation
perl -MConfig -e 'print $Config{archlib},"\n"'

will give you the directory where things need to go.

The pm file goes directly in archlib. The sharedlib and the bootstrap
file go in <archlib>/auto/<extension-name>

<archlib>/Postgres.pm
<archlib>/auto/Postgres/Postgres.so
<archlib>/auto/Postgres/Postgres.bs

That would be a start.
