Hello,
On trying to drop an index named "employer_employerid_key" which supports a
unique constraint:
"employer_employerid_key" UNIQUE CONSTRAINT, btree (employerid)
I get this error:
ERROR: cannot drop index employer_employerid_key because constraint
employer_employerid_key on table employer requires it
HINT: You can drop constraint employer_employerid_key on table employer
instead.
I'm using the CASCADE and IF EXISTS arguments and the docs say nothing
about any special cases (
https://www.postgresql.org/docs/9.3/static/sql-dropindex.html). This is
with PostgreSQL 9.3.15.
The actual command is:
drop index if exists employer_employerid_key cascade;
Any ideas if this is normal or why it happens?
