DatabasePostgres::limitResult | ( | $ | sql, | |

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.

DatabasePostgres::tableName | ( | $ | name | ) |
Format a table name ready for use in constructing an SQL query.
This does two important things: it quotes the table names to clean them up, and it adds a table prefix if only given a table name with no quotes.
All functions of this object which require a table name call this function themselves. Pass the canonical name to such functions. This is only needed when calling query() directly.
$name | String: database table name |
