When our XML-handling modules were first written, the SQL standard lacked any error codes that were particularly intended for XML error conditions. Unsurprisingly, this led to some rather random choices of errcodes in those modules. Now the standard has a whole SQLSTATE class, "Class 10 - XQuery Error", with a reasonably large selection of relevant-looking errcodes. In this patch I've chosen one fairly generic code defined by the standard, 10608 = invalid_argument_for_xquery, and used it where it seemed appropriate. I've also made an effort to replace ERRCODE_INTERNAL_ERROR everywhere it was not clearly reporting a coding problem; in particular, many of the existing uses look like they can fairly be reported as ERRCODE_OUT_OF_MEMORY. It might be interesting to try to map libxml2's error codes into the standard's new collection, but I've not undertaken that here. Discussion: https://postgr.es/m/417250.1726341268@sss.pgh.pa.us |
