Hi All, I have just installed postgres 8.1.2 (upgrading from 7.4.2) and upon commencement of populating DBs with data dumped using pg_dumpall(7.4.2) I receive the following error: DELETE FROM pg_shadow WHERE usesysid <> (SELECT datdba FROM pg_database WHERE datname = 'template0'); ERROR: cannot delete from a view HINT: You need an unconditional ON DELETE DO INSTEAD rule. DELETE FROM pg_group; ERROR: cannot delete from a view HINT: You need an unconditional ON DELETE DO INSTEAD rule. The DBs were created etc and everything seems to be progressing as expected. Are the above errors critical or of any major concern or can they be ignored??? Thanks ENZO...
