I understand every word of it. Why doesn't that error come up after the first
CREATE DOMAIN error, since I was in a transaction. Then it would of been
perfectly clear that the transaction I was in needed to be rolled back. Rather
that error doesn't occur until the second valid CREATE DOMAIN is executed.
I was not aware of what Stephan indicated: "All errors are considered
unrecoverable ones by PostgreSQL so after any error the transaction is in an
effectively unusable state and should be rolled back". I know better now. It
still seams that the "queries ignored until end of transaction block" should of
been thrown after the first invalid CREATE DOMAIN. That's all.
