[GENERAL] Compression function

2015-06-16 Thread Leonardo M. Ramé
Hi, does anyone know if there's a compression function to let me store in gzipped/deflate format TEXT or Bytea fields. Please correct me if I'm wrong, but I also wonder if this function is really needed since I've read large objects are stored with TOAST, hence compression is already there.
