A table has a unique constraint on a column that needs removing. Reading
the
postgres-12.x docs for alter table it appears the correct syntax is:
alter table locations drop constraint unique;
It should be:
alter table locations drop constraint 'constraint_name';
Where you can find 'constraint_name' from:
\d locations
but this is wrong.
Trying 'alter table locations alter column loc_nbr drop constraint
unique;' also
failed.
What's the proper syntax to drop the unique constraint on a table column?
TIA,
Rich
