The following documentation comment has been logged on the website:

Description:
Hello
I've noticed, if two transactions in read committed mode are trying to
insert same value to unique column, second transaction INSERT will wait for
the first transaction commit or rollback. Can't see this behavior explicitly
stated in the doc about transaction isolation modes.
Thank you
You are doing a great job with PostgreSQL docs!
