Hi, There's a number of symbols that are exported by libpq that are also in binaries (mostly via pgport). That strikes me as not great, because the behaviour in those cases isn't particularly well defined / OS dependent / linker option dependent.
How about renaming those functions, turning the functions exported by libpq into wrappers? This is at least: pqsignal pg_char_to_encoding pg_valid_server_encoding_id pg_valid_server_encoding pg_encoding_to_char pg_utf_mblen I'm not quite sure why we export some of these, but we likely don't want to change that, given the API/ABI break that'd cause. Greetings, Andres Freund
