You seem to have ignored the warning telling you this probably wasn't
a good idea:
regression=# create view view1 as select null as col1;
WARNING: column "col1" has type "unknown"
DETAIL: Proceeding with relation creation anyway.
CREATE VIEW
regression=#
According to the letter of the SQL standard, the above is illegal;
you're really supposed to CAST the null to some specific datatype.
If we were to change anything in response to this complaint, it'd
probably be to promote the WARNING to an ERROR.
