Thanks! It looks like if get_database_list were not static, it would be just the thing I'm looking for. Would an SPI query of pg_database also work, in the bgw-connected-to-null-dbname context? I'm just wondering if that might be clearer/fewer LOC than just copying the lower-level approach from get_database_list. -Chap
