Formerly, Catalog.pm turned a C array type declaration in the catalog header files into a SQL type, e.g., 'foo[]'. Along the way, genbki.pl turned this into '_foo' for the purpose of type lookups, but wrote 'foo[]' to postgres.bki. During bootstrap, bootscanner.l had to have a special case rule to tokenize this, and then MapArrayTypeName() would turn 'foo[]' into '_foo' one more time. This seems unnecessarily complicated, especially since nobody cares that much about the readability of postgres.bki. Instead, make Catalog.pm convert the C declaration into '_foo' to start with, and preserve that representation of the type name throughout bootstrap data processing. Then rip out the special-case code in bootscanner.l and bootstrap.c. This changes postgres.bki to the extent that array fields are now declared like proconfig = _text , rather than proconfig = text[] , No documentation update, since the SGML docs didn't mention any of this in the first place, and it's all pretty transparent to writers of catalog header files anyway.

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: https://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.
