The logical replication type map seems to have been misused by its only caller -- it would try to use the remote OID as input for local type routines, which unsurprisingly could result in bogus "cache lookup failed for type XYZ" errors, or random other type names being picked up if they happened to use the right OID. Fix that, changing Oid logicalrep_typmap_getid(Oid remoteid) to char *logicalrep_typmap_gettypname(Oid remoteid) which is more useful. If the remote type is not part of the typmap, this simply prints "unrecognized type" instead of choking trying to figure out -- a pointless exercise (because the only input for that comes from replication messages, which are not under the local node's control) and dangerous to boot, when called from within an error context callback. Once that is done, it comes to light that the local OID in the typmap entry was not being used for anything; the type/schema names are what we need, so remove local type OID from that struct. Once you do that, it becomes pointless to attach a callback to regular syscache invalidation. So remove that also.

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: https://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 https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
