Michael Paquier b8da37b3ad Rework pg_input_error_message(), now renamed pg_input_error_info()
pg_input_error_info() is now a SQL function able to return a row with
more than just the error message generated for incorrect data type
inputs when these are able to handle soft failures, returning more
contents of ErrorData, as of:
- The error message (same as before).
- The error detail, if set.
- The error hint, if set.
- SQL error code.

All the regression tests that relied on pg_input_error_message() are
updated to reflect the effects of the rename.

Per discussion with Tom Lane and Andrew Dunstan.

Tom Lane eb8312a22a Detect bad input for types xid, xid8, and cid.
Historically these input functions just called strtoul or strtoull
and returned the result, with no error detection whatever.  Upgrade
them to reject garbage input and out-of-range values, similarly to
our other numeric input routines.

To share the code for this with type oid, adjust the existing
"oidin_subr" to be agnostic about the SQL name of the type it is
handling, and move it to numutils.c; then clone it for 64-bit types.

Because the xid types previously accepted hex and octal input by
reason of calling strtoul[l] with third argument zero, I made the
common subroutine do that too, with the consequence that type oid
now also accepts hex and octal input.  In view of 6fcda9aba, that
seems like a good thing.

While at it, simplify the existing over-complicated handling of
syntax errors from strtoul: we only need one ereturn not three.

Tom Lane 47f3f97fcd Convert a few more datatype input functions to report errors softly.
Convert assorted internal-ish datatypes, namely aclitemin,
int2vectorin, oidin, oidvectorin, pg_lsn_in, pg_snapshot_in,
and tidin to the new style.

(Some others you might expect to find in this group, such as
cidin and xidin, need no changes because they never throw
errors at all.  That seems a little cheesy ... but it is not in
the charter of this patch series to add new error conditions.)

Amul Sul, minor mods by me

Thomas Munro 4c04be9b05 Introduce xid8-based functions to replace txid_XXX.
The txid_XXX family of fmgr functions exposes 64 bit transaction IDs to
users as int8.  Now that we have an SQL type xid8 for FullTransactionId,
define a new set of functions including pg_current_xact_id() and
pg_current_snapshot() based on that.  Keep the old functions around too,
for now.

It's a bit sneaky to use the same C functions for both, but since the
binary representation is identical except for the signedness of the
type, and since older functions are the ones using the wrong signedness,
and since we'll presumably drop the older ones after a reasonable period
of time, it seems reasonable to switch to FullTransactionId internally
and share the code for both.

Thomas Munro aeec457de8 Add SQL type xid8 to expose FullTransactionId to users.
Similar to xid, but 64 bits wide.  This new type is suitable for use in
various system views and administration functions.
