And so I came up with three patches to make errcodes.h, plerrcodes.h and
errcodes.sgml (respectively) generated files.
The autogenerated files are almost identical with the originals (except
for formatting, sometimes, and comments) except:
* in errcodes.sgml the Meaning field for INVALID ARGUMENT FOR NTH_VALUE
FUNCTION changed to INVALID ARGUMENT FOR NTH VALUE FUNCTION. Not ideal,
but I wouldn't shed any tears. The Constant field stays the same, and
that's what's important for a PL/pgSQL programmer
* in errcodes.h there are a few changes like that:
#define ERRCODE_DATETIME_FIELD_OVERFLOW MAKE_SQLSTATE('2','2',
'0','0','8')
-#define ERRCODE_DATETIME_VALUE_OUT_OF_RANGE ERRCODE_DATETIME_FIELD_OVERFLOW
+#define ERRCODE_DATETIME_VALUE_OUT_OF_RANGE
MAKE_SQLSTATE('2','2','0','0','8')
#define ERRCODE_DIVISION_BY_ZERO MAKE_SQLSTATE('2','2',
'0','1','2')
unless your MAKE_SQLSTATE macro has side-effects, it should not be a problem
* in plerrcodes.h a few entries disappeard, and that's because they had
duplicated SQLSTATE values. As they were not documented in
errcodes.sgml, no one should even know they existed, and as they catch
the same SQLSTATE, again it shouldn't be an issue.
As a bonus, a documented but forgotten exception got added. Try this in
HEAD:
do $$ begin begin exception when nonstandard_use_of_escape_character
then null; end; end$$;
It will fail.
Cheers,
Jan
