Re: tsearch Parser Hacking

David,

as a cool perl guy you can easily take OpenFTS (openfts.sourceforge.net),
which provides perl interface to tsearch datatypes, and develop a
plperl version. That would be interesting for many people, who like flexibility
of perl. We personally use openfts in our web projects,i.e., we use tsearch as
a storage and we prepare tsvector externally. Openfts distribution contains
tests, examples of dictionaries, parser. Current interface of configuration
is ugly, but it should be not difficult to write table driven configuration.

What do you think ?
