I have one table (call it "master") that, among other things, contains a
serial number. I have a number of other tables (call them "slaves") that,
among other things, contain a foreign key referring to the serial number in
the first table. I will be inserting one row into the master table, and one
row into zero or more slave tables in each transaction.
What I want to do is use a sequence in the master table to let PostgreSQL
automatically generate a unique serial number for me, but I need to know the
serial number in order to insert the corresponding rows into the slave
table(s). Is there any way of retrieving the serial number that will be used
before the transaction has been committed? Or will I have to generate my own
serial numbers?
