$result
[, int $row
[, int $result_type = PGSQL_ASSOC
]] )$result
[, int $row

NULL.
Speed-wise, the function is identical to pg_fetch_array(), and almost as fast as pg_fetch_row() (the difference is insignificant).
result
PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).
row
Row number in result to fetch. Rows are numbered from 0 upwards. If
omitted or NULL, the next row is fetched.
result_type
Ignored and deprecated.
class_name
The name of the class to instantiate, set the properties of and return. If not specified, a stdClass object is returned.
params
An optional array of parameters to pass to the constructor
for class_name objects.
An object with one attribute for each field
name in the result. Database NULL
values are returned as NULL.
FALSE is returned if row exceeds the number
of rows in the set, there are no more rows, or on any other error.

| 4.3.0 |
result_type default changed from
PGSQL_BOTH to PGSQL_ASSOC,
since the numeric index was illegal.
