Hi guys,
I've got this domain:
CREATE DOMAIN public.a_city
AS character varying(80)
COLLATE pg_catalog."default";
And I need to increase the type from character varying(80) to
character varying(255).
How can I do that? didn't find info about it. I'm using Postgres 9.2
Thanks!
Patrick
Why not simply use the 'text' data type?
To change the data type on a column you can use:
ALTER [ COLUMN ] /column_name/ [ SET DATA ] TYPE /data_type/ [ COLLATE
/collation/ ] [ USING /expression/ ]
see:
https://www.postgresql.org/docs/9.2/static/sql-altertable.html
Note that 9.5 is the latest version of pg, with 9.6 being released very soon!
Cheers,
Gavin
