A range type can name another range type as its subtype, and a record type can bear a column of another record type. Consequently, functions like range_cmp() and record_recv() are recursive. Functions at risk include operator family members and referents of pg_type regproc columns. Treat as recursive any such function that looks up and calls the same-purpose function for a record column type or the range subtype. Back-patch to 9.0 (all supported versions). An array type's element type is never itself an array type, so array functions are unaffected. Recursion depth proportional to array dimensionality, found in array_dim_to_jsonb(), is fine thanks to MAXDIM. |

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: http://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
