Thread: domain check constraint syntax problem for 7.4

I am trying to create a domain with more than one check constraint and
I am getting an error that I don't think is correct according to the
documentation. I am not sure if this is a limitation of a partially
implemented feature or a bug that has so far been overlooked.

For example:
area=# create domain test6 as int constraint ack check(value<4);
CREATE DOMAIN
area=# create domain test7 as int constraint ack check(value<4),
area-# constraint ack1 check(value>0);
ERROR:  parser: syntax error at or near "," at character 57
area=# create domain test7 as int check(value<4), check(value>0);
ERROR:  parser: syntax error at or near "," at character 42

They work the same as table constraints with in-line declaration (no
comma).

OK. But the documentation implies there is a comma, so it should probably
get chenged then.

This is from the create domain documentation:
CREATE DOMAIN domainname [AS] data_type   [ DEFAULT default_expr ]   [ constraint [, ... ] ]

I would have expected the last line to be:   [ constraint [ ... ] ]
if there weren't supposed to be commas.

Thanks for the help.
