+SYNOPSIS
+        #include <pgsql.h>
+
+        int pg_query (string query)
+        int pg_query (string query, int flags)
+
+DESCRIPTION
+        Queue a new query <query> to the database connection on the current
+        object. Return the unique id of the query. The query result itself
+        will be passed as argument to the callback function.
+
+        <flags> can be one of these values:
+          PG_RESULT_ARRAY: Pass the query result as array.
+          PG_RESULT_MAP:   Pass the query result as mapping.
+
+        The function is available only if the driver is compiled with
+        PostgreSQL support. In that case, __PGSQL__ is defined.
+
+        The efun triggers a privilege violation ("pgsql", "pg_query").
+
+HISTORY
+        Added in 3.3.445.
+        LDMud 3.3.640 added the privilege violation.
