I have 2 databases and want to implement triggers on table update of database1 to do do some updates on database2’s tables.
Example:
db1 has a table 1t1
db2 has a table 2t1
on inserting a touple into 1t1 i want to insert corresponding touple into 2t1
As of now Im using postgresql, but I dont mind switching to other free databases.
How to achieve this?
I suggest to use database link to establish a connection between two remote DB.
Take a look to this page:
http://www.postgresql.org/docs/current/static/contrib-dblink-connect.html
There is also a good tutorial here:

bye,
