The standard calls this error variable SQLSTATE
(look up in ESQL standard)
first 2 chars are class next 3 are subclass
"00000" is e.g. Success
"02000" is Data not found
"U0xxx" user defined routine error xxx is user defined
> /* somewhere... */

PGELOG(ERROR, PGSQLSTATE_TYPE, ("type %s cannot be created because it already exists",
...))
put varargs into parentheses to avoid need for ... macros see Tom's proposal
I also agree, that we can group different text messages into the same SQLSTATE,
if it seems appropriate for the client to handle them alike.
