Is there a way to reset the primary key of a PostgreSQL table to start at 1 again on a populated table?
Right now it’s generating numbers from 1000000 and up. I want it all to reset and start to 1, keeping all my existing data intact.

Primary keys that autoincrement (i.e., columns with data type
serial primary key) are associated with a sequence. You can set the next value for any sequence using thesetval(<seqname>, <next_value>)function. Note that to actually execute the function by itself you need to useSELECT, like this:SELECT setval(<seqname>, <next_value>)The name of the auto created sequences when using serial are
<table>_<column>_seq
