No, it isn't. Describe accepts both prepared statement and portal names.
In the former case, it returns ParameterDescription message as well as
the RowDescriptions it returns for the latter.

Yes, you do. Bind accepts 0 (use the default text format), 1 (use this
format for all results), or as many result format specifiers as there
are results.

Execute can be told to return no more than n rows of results. If there
are more rows available, the server returns PortalSuspended and awaits
another Execute message. The default of 0 imposes no limit.
Please read protocol-flow.html and protocol-message-formats.html.
