Looks good to me. > I added a bunch of tests for various built-in conversions. Nice! I would like to have utf8 tests for every category of invalid byte (overlong, surrogate, 5 bytes, etc), but it's not necessary for this patch. > I spent some time refactoring and adding comments all around the patch, > hopefully making it all more clear.

The comments and renaming are really helpful in understanding that file! Although a new patch is likely forthcoming, I did take a brief look and found the following: In copyfromparse.c, this is now out of date: * Read the next input line and stash it in line_buf, with conversion to * server encoding. One of your FIXME comments seems to allude to this, but if we really need a difference here, maybe it should be explained: +#define INPUT_BUF_SIZE 65536 /* we palloc INPUT_BUF_SIZE+1 bytes */ +#define RAW_BUF_SIZE 65536 /* allocated size of the buffer */ Lastly, it looks like pg_do_encoding_conversion_buf() ended up in 0003 accidentally? -- John Naylor EDB: http://www.enterprisedb.com
