The following bug has been logged online:
Bug reference: 1305
Logged by: Károly Segesdi
Email address: jazzkutya@wom.hu
PostgreSQL version: 7.4.5
Operating system: slackware 10.0
Description: can't use the type 'number' with alter table
Details:
somedb=# alter table sometbl add column msisdn number(11);
ERROR: syntax error at or near "(" at character 43
you can use the type identifier 'decimal' instead:
somedb=# alter table sometbl add column msisdn decimal(11);
ALTER TABLE
The documentation says theese two types are the same, but it's annoying that
you can't use the one that is mentioned more frequently in the docs.
postgresql version is 7.4.6, your bugreport form's version field misses this
version.
