Ok, I just added pg_verifymbstr() instead of changing the result type. I didn't add any additinal file reading functions in the patch, but I'm willing to add them if someone want them: - pg_read_file_with_encoding() - pg_read_binary_file() RETURNS bytea - pg_read_text_file() RETURNS SETOF text -- returns set of lines One thing bothering me is the HINT message on error is just pointless; The encoding is controlled by "server_encoding" here. We will have the same error message in server-side COPY commands. We'd better improving the message, though it should be done by another patch. =# SELECT pg_read_file('invalid.txt', 0, (pg_stat_file('invalid.txt')).size); ERROR: invalid byte sequence for encoding "UTF8": 0x93 HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding". =# COPY tbl FROM 'invalid.txt'; -- server-side copy from a local file. (the same message -- but the encoding should match with "server_encoding") Regards, --- Takahiro Itagaki NTT Open Source Software Center
