Hi,

I am trying to update a tsvector field through a plperl trigger.

$_TD->{new}{text_search} = to_tsvector('pg_catalog.english', 'text1 text2');


You need to wrap that into an actual SPI call at the very least. Database procedures are not available natively for PL languages in general (minus perhaps pl/pgsql).

 Something like:

$_TD->{new}{text_search} = spi_exec_query("to_tsvector('pg_catalog.english', ". quote_literal('text1 text2') .";")->{rows}[0]{to_tsvector};

If performance is any consideration, I suspect pl/pgsql would be the clear winner.
