Thread: pgsql: Add missing copyfuncs/equalfuncs support for

Log Message:
-----------
Add missing copyfuncs/equalfuncs support for AlterTSDictionaryStmt and
AlterTSConfigurationStmt.  All utility statement node types are expected
to be supported here, though they do not have to have outfuncs/readfuncs
support.  Found by running regression tests with COPY_PARSE_PLAN_TREES
enabled.
