Обсуждение: pgsql: Allow CREATE TABLE (LIKE ...) from composite type

Allow CREATE TABLE (LIKE ...) from composite type

The only reason this didn't work before was that parserOpenTable()
rejects composite types.  So use relation_openrv() directly and
manually do the errposition() setup that parserOpenTable() does.
