Description:
The explanation of the behaviour of temporary tables could be clearer. In
particular, there is no statement that categorically says that rows in the
temporary table are only visible to the current session -- there is
information to that effect in the Compatibility section on adherence to the
SQL standard, but I would suggest adding the sentence:
Data written to temporary tables is only visible to the current session.
after the sentence:
If specified, the table is created as a temporary table.
akin to how unlogged is defined in the paragraph following.
