Tom Lane a916b47e23 Clean up usage of bison precedence for non-operator keywords. Assigning a precedence to a keyword that isn't a kind of expression operator is rather dangerous, because it might mask grammar ambiguities that we'd rather know about. It's much safer to attach explicit precedences to individual rules, which will affect the behavior of only that one rule. Moreover, when we do have to give a precedence to a non-operator keyword, we should try to give it the same precedence as IDENT, thereby reducing the risk of surprising side-effects. Apply this hard-won knowledge to SET (which I misassigned ages ago in commit `2647ad658`) and some SQL/JSON-related productions (from commits `6ee30209a`, `71bfd1543`). Patch HEAD only, since there's no evidence of actual bugs here. Discussion: https://postgr.es/m/CADT4RqBPdbsZW7HS1jJP319TMRHs1hzUiP=iRJYR6UqgHCrgNQ@mail.gmail.com		2 years ago

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.

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, and related software, may be
obtained at https://www.postgresql.org/download/.  For more information
look at our web site located at https://www.postgresql.org/.
