Where are the records coming from? Are they inside the database?
(If not, why do you care about integrating this with Postgres?)
It seems like the right way to integrate this sort of functionality
is to turn it into a kind of index, so that you can do
SELECT * FROM mytable WHERE keyfield ~~~ 'search string';
where ~~~ is the name of some operator that is associated with the
index. The temporary-table approach you are taking seems inherently
klugy, and would still be awkward even if we had functions returning
recordsets...
