> inheriting pk and triggers
pg inheritance is quite limited. what i (and i'm sure many others)
have done is:
1. create master sequence
2. create base table
3. create base trigger procedures
4. create derived tables, using "inherit"
5. write procedure p( table_name ) thata) sets pk of table_name using master sequenceb) attaches base trigger
proceduresonto table_name
6. run procedure p() against each derived table
another way to skin this cat is to use "objects" in the database:
-- base table
table common( int id primary key ..., ref_tab name, -- name of secondary table using common ... -- common
columnsand constraints
) without oids;
-- secondary table
table secondary1( int id1 not null references common(id), int id2 primary key, -- (can use id1 as pk!) ...
-- secondary columns and constraints
) without oids;
-- views for secondary table - generate!
create secondary1_v1 as select c.*, s.*
from secondary1 s join common c on( s.id1 = c.id );
-- (if you want) dml for view to make life easier - generate!
...
if you are maintaining the common info, or if you want a many to one
secondary to master, this approach is easier.
