pgsql: Fix catalog data of new LO privilege functions

Fix catalog data of new LO privilege functions

This commit improves the catalog data in pg_proc for the three functions
for has_largeobject_privilege(), introduced in 4eada203a5a8:
- Fix their descriptions (typos and consistency).
- Reallocate OIDs to be within the 8000-9999 range as required by
a6417078c414.

Bump catalog version.
