Add foreign key validation
Closes #15
Actually this depends because I retried this and I only get an ShareRowExclusiveLock
to the table being referenced in Postgres 9.5 + thanks to this patch BUT removing foreign keys still takes an AccessExclusiveLock
.
Any chance to have this merged soon and have a new version released? Quite recently, I had a very unfortunate issue with large table and adding a foreign key constraint and this addition would have been definitely helpful then.
