When doing such a partial metastore update for a specific table, then
the types (GTypes) of all fields collapse to gchararray (at least for
postgresql). Do I maybe need to update something else than "_tables" to
get the column types correctly?

Here is a testcase. After doing a complete metastore update, the types
are correct, but when doing a partial update after that (without
changing anything else in the database), all types become gchararray:
