<para>
LIMIT allows you to retrieve just a portion of the rows that are
generated by the rest of the query. If a limit count is given, no
more than that many rows will be returned. If an offset is given,
that many rows will be skipped before starting to return rows.
more than that many rows will be returned.
LIMIT ALL is the same as omitting a LIMIT clause.

to the client. OFFSET 0 is the same as omitting an OFFSET clause.
If both OFFSET and LIMIT appear, then OFFSET rows are skipped before
starting to count the LIMIT rows that are returned.
