Two tables have a sequence for the PK. Over time I manually entered the PK

I just tried to set one table's PK sequence to the current max(PK) value
using this _expression_ from a stackexchange thread:
SELECT setval('<sequence_name>', <current_max_number>, true); -- next value will be max(PK) + 1
Needing to add a new row to a table for a specific industry table (with 52
rows) I set the PK as DEFAULT in the INSERT INTO _expression_. To my surprise
and disappointment all 52 rows now have the company_name column as the newly
inserted name. Feh! I need to restore all the correct names for each PK.
If the table has a primary key, then the command should have failed with a duplicate key error as soon as the first dupe was discovered.
What does your table definition look like?
