SQL has standardized on => as the use of to specify named parameters, and we've wanted for many years to support the same syntax ourselves, but this has been complicated by the possible use of => as an operator name. In PostgreSQL 9.0, we began emitting a warning when an operator named => was defined, and in PostgreSQL 9.2, we stopped shipping a =>(text, text) operator as part of hstore. By the time the next major version of PostgreSQL is released, => will have been deprecated for a full five years, so hopefully there won't be too many people still relying on it. We continue to support := for compatibility with previous PostgreSQL releases. Pavel Stehule, reviewed by Petr Jelinek, with a few documentation tweaks by me. |
