Hi Michael,
The problem of offsets seems to be universal. If there is a structure
within structure. The offset to the members of inner structure should be
the size of the outer structure and not size of inner structure. Applying
this rule recursively, offset to the member of any nested structure, a

Well, we don't supported Infinity and NaN in json(b), as well as Json

Now we need a script, which generated nice html table.

I'd like to do some changes to the WAL format in 9.5. I want to annotate
each WAL record with the blocks that they modify. Every WAL record
already includes that information, but it's done in an ad hoc way,

currently part of the WA

Seems reasonable, especially if we can make the buffer numbering business
less error-prone.
