At this very moment, the first snapshot of pgAdmin III 1.3 is uploading,
which includes the pgsql configuration file editor.
For pginstaller purposes, the command line
pgadmin3 -c <pgsql-datadir>
or pgadmin3 -ch <pgsql-dir>\pg_hba.conf
or pgadmin3 -cm <pgsql-dir>\postgresql.conf
handles the configuration files. If pginstaller should have
additional/different requirements, please let us know.
Regards,
Andreas
