Maybe you could just import the second database into another schema of
the first database if it's urgent...

Otherwise the nature of conflicts will have to be thought through, like

- Are there some data that exist in both databases - i.e. which become
duplicates if both tables are merged?

- Are the serials used as foreign keys in other tables or as the basis of
any other fields?

- Can the serials be changed to different numbers - e.g., is it ok or even
needed to convert "11" on database B to "10011" on database A and so on,
to avoid conflict two ID 11 records having different data?

- Does the order of records matter?

Once the problem is familiar, many gurus will be able to help. I just
wanted to provide a starter.
