Subject: [PATCH] Fix operator naming in pg_trgm GUC option descriptions

Descriptions of pg_trgm GUC options have % replaced with %% like it was
a printf-like format.  But that's not needed since they are just plain strings.
This commit fixed that.  Backpatch to last supported version since this error
present from the beginning.
