Hi Parwa,
The database you are using is probably Chado, that database that sits under
a Tripal instance (and is used in other settings too). The schema you are
probably using is 1.31 which has been around for a long time. The primary
keys of all of the tables are auto incrementing bigserials (bigints). The
schema is defined here:
https://raw.githubusercontent.com/GMOD/Chado/1.31/chado/modules/default_schema.sql
And more information can be found from the gmod web site:
https://gmod.org/wiki/Introduction_to_Chado
Generally, PostgreSQL manages the creation of new primary keys on INSERT.
Please let us know if you have any other questions,
Scott
