First fruits of all that work on error message rejiggering ...
regression=# \set VERBOSE terse
regression=# select 1!! ;
ERROR: operator does not exist: integer !!
regression=# \set VERBOSE default
regression=# select 1!! ;
ERROR: operator does not exist: integer !!
HINT: No operator matches the given name and argument type(s). You may need to add
explicit typecasts.
regression=# \set VERBOSE verbose
regression=# select 1!! ;
ERROR: 42883: operator does not exist: integer !!
HINT: No operator matches the given name and argument type(s). You may need to add
explicit typecasts.
LOCATION: op_error, parse_oper.c:691
regression=# select 'z' && 'q';
ERROR: 42725: operator is not unique: "unknown" && "unknown"
HINT: Unable to choose a best candidate operator. You may need to add explicit
typecasts.
LOCATION: op_error, parse_oper.c:684
Before we go too much further, does this look sane to people?
Any adjustments you want to make around the edges?
(BTW, if you're wondering where the 42xxx error codes came from,
I borrowed them from DB2. The SQL99 spec seems happy to lump
all sorts of conditions under 42000 "syntax error or access
violation" ...)
