Tom Lane 0d18852666 Disallow CREATE INDEX if table is already in use in current session. 
If we allow this, whatever outer command has the table open will not know
about the new index and may fail to update it as needed, as shown in a
report from Laurenz Albe.  We already had such a prohibition in place for
ALTER TABLE, but the CREATE INDEX syntax missed the check.

Fixing it requires an API change for DefineIndex(), which conceivably
would break third-party extensions if we were to back-patch it.  Given
how long this problem has existed without being noticed, fixing it in
the back branches doesn't seem worth that risk.
