See KEEPONLYALNUM in pg_trgm/trgm.h ... Now, using a custom-modified pg_trgm module in production is likely not something you want to do for long. It might be interesting to look into whether the relatively-recently-invented "operator class parameter" mechanism could be exploited to allow this behavior to be customized without hacking C code. regards, tom lane
