Re: Primary key constraints

Kumar,

You can drop a sequence by doing:

drop sequence experiment_exp_id_seq;

See the documentation here:

http://www.postgresql.org/docs/8.0/static/sql-dropsequence.html

However, that should happen automatically if it was defined as a serial and
you dropped the table, so I'm not sure what is going on. If the drop
sequence doesn't work, perhaps you could tell us what the table definition
for experiment used to look like and what your table def for study now looks
like.
