Re: Testing for a shared library

As you know, presence of shared library doesn't mean precense of module in db :).

You can try selecting:

# select count(*) from pg_opclass where opcname = 'tsvector_ops';

or, more general,

# select count(*) from pg_proc where probin = '$libdir/tsearch2';

But not all modules adds new function...
