I proposed in https://www.postgresql.org/message-id/19581.1538077...@sss.pgh.pa.us that we should remove pqsignal, as well as pg_utf_mblen pg_encoding_to_char pg_char_to_encoding pg_valid_server_encoding pg_valid_server_encoding_id from libpq's exports, on the grounds that (a) nobody should be using those (they're undocumented as exports), and (b) anybody who is using them should get them from libpgport/libpgcommon instead.
