We have a not-terribly-thoroughly-enforced-yet project policy that internal
errors with SQLSTATE XX000 (ie, plain elog) should not be triggerable from
SQL. record_in, domain_in, and PL validator functions all failed to meet
this standard, because they threw plain elog("cache lookup failed for XXX")
errors on bad OIDs, and those are all invokable from SQL.
For record_in, the best fix is to upgrade typcache.c (lookup_type_cache)
to throw a user-facing error for this case. That seems consistent because
it was more than halfway there already, having user-facing errors for shell
types and non-composite types. Having done that, tweak domain_in to rely
on the typcache to throw an appropriate error. (This costs little because
InitDomainConstraintRef would fetch the typcache entry anyway.)
For the PL validator functions, we already have a single choke point at
CheckFunctionValidatorAccess, so just fix its error to be user-facing.

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: http://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
