Alexander Korotkov 927d9abb65 Support for ISO 8601 in the jsonpath .datetime() method
The SQL standard doesn't require jsonpath .datetime() method to support the
ISO 8601 format.  But our to_json[b]() functions convert timestamps to text in
the ISO 8601 format in the sake of compatibility with javascript.  So, we add
support of the  ISO 8601 to the jsonpath .datetime() in the sake compatibility
with to_json[b]().

The standard mode of datetime parsing currently supports just template patterns
and separators in the format string.  In order to implement ISO 8601, we have to
add support of the format string double quotes to the standard parsing mode.

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:

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
