Saluton,
I am using
,----
| SELECT version();
| version
| --------------------------------------------------------------------
| PostgreSQL 7.0.2 on i586-pc-linux-gnulibc1, compiled by gcc 2.95.1
| (1 row)
`----
, and upgrading to 7.1 is not possible (it was hard enough to get the
admin to upgrade from 6.5.3).
While the docs say that I can create a rule on table.column, I get the
error message:
,----
| litdb=> create rule no_update_on_journal_title__rl as
| litdb-> on update to journal.title do instead nothing;
| ERROR: attribute level rules currently not supported
`----
Am I doing something wrong here, or do I have to work around this via
... where old.title = new.title ... (would this work?), or should I
use a before-trigger?
Are ``attribute level rules'' supported in 7.1 (so I can at least put
a note into the code)?
Thanks in advance,
Albert.
