In December I had tried this; it caused a tremendous slowdown in our system.
I have avoided it since then.
Do you expect pg_trgm to work with phrases? OI had read a post earlier from
an earlier support question that suggested that it I SHOULD expect
performance to degrade and that pg_trgrm was oriented towards word mathcing,
not phrase matching.

I'm a bit unsure from reading your mail -- have you tried pg_trgm with a
GiST
index?

choose an index scan if your joining column's datatypes do not
match
