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.

Parsing a postgres array can be a tricky problem, he's my take on this, it handles multi-dimensional arrays plus escaping using a nasty regexp to determine the limits of each data-item.
This should really be handled by PHP PostgreSQL module

The equivalent of IDatabase::select() except that the constructed SQL is returned, instead of being immediately executed.
This can be useful for doing UNION queries, where the SQL text of each query is needed. In general, however, callers outside of Database classes should just use select().

Wikimedia\Rdbms\DatabasePostgres::tableName | ( | $name, | |
$format = 'quoted' |
|||
) |
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.
string | $name | Database table name |
string | $format | 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 |

The result is unquoted, and needs to be passed through addQuotes() before it can be included in raw SQL.
