An PgSql\Result instance, returned by pg_query, pg_query_params or pg_execute(among others).
Row number in result to fetch. Rows are numbered from 0 upwards. If omitted, next row is fetched.
A string representing the name of the field (column) to fetch, otherwise an int representing the field number to fetch. Fields are numbered from 0 upwards.
Boolean is returned as "t" or "f". All other types, including arrays are returned as strings formatted in the same default PostgreSQL manner that you would see in the psql program. Database NULL values are returned as null.
false is returned if row exceeds the number of rows in the set, or on any other error.
|8.1.0||The result parameter expects an PgSql\Result instance now; previously, a resource was expected.|
