Обсуждение: pgsql: New json functions.
New json functions. json_build_array() and json_build_object allow for the construction of arbitrarily complex json trees. json_object() turns a one or two dimensional array, or two separate arrays, into a json_object of name/value pairs, similarly to the hstore() function. json_object_agg() aggregates its two arguments into a single json object as name value pairs. Catalog version bumped. Andrew Dunstan, reviewed by Marko Tiikkaja.

*sigh* forgot to mention that json_to_record() is also included. It turns a json argument into whatever record type is expected by the call.

A typo: s/agument/argument/ Also, these are changes that probably aren't essential, but makes some sentences clearer: s/heterogeneously typed/heterogeneously-typed/ s/two argument form/two-argument form/ s/one argument form/one-argument form/ s/type coercion/type-coercion/ -- Thom
