DatabasePostgres::limitResult	(	$	sql,
		$	limit,
		$	offset = `false`
	)

Construct a LIMIT query with optional offset.

This is used for query pages. The SQL should be adjusted so that only the first $limit rows are returned. If $offset is provided as well, then the first $offset rows should be discarded, and the next $limit rows should be returned. If the result of the query is not ordered, then the rows to be returned are theoretically arbitrary.

$sql is expected to be a SELECT, if that makes a difference. For UPDATE, limitResultForUpdate should be used.

The version provided by default works in MySQL and SQLite. It will very likely need to be overridden for most other DBMSes.

Parameters:

$sql	String SQL query we will append the limit too
$limit	Integer the SQL limit
$offset	Integer\|false the SQL offset (default false)

Returns:: string

Reimplemented from DatabaseBase.

Parameters:

$name	String: database table name
$format	String One of: quoted - Automatically pass the table name through addIdentifierQuotes() so that it can be used in a query. raw - Do not add identifier quotes to the table name
