Re: [HACKERS] [PATCH] Generic type subscripting - Mailing list pgsql-hackers

here is a attached fixed first patch

v30-0001-Base-implementation-of-subscripting-mechanism.patch

My objectives are fixed. I checked this patch and

There are not problems with build (code, documentation)

All tests passed

The code is well documented

I like the functionality introduced by this patch. It opens a door for easy work with json, jsonb, xml, ... and lot of other types with array access syntax.

This is first step, but necessary steps. A write operations are not supported by PL/pgSQL. But plpgsql developers still has some benefits. It is working for read operations (in plpgsql).

I'll mark this patch as ready for commiters

Thank you for your work.

Regards

Pavel
