Copied from TUWF::Validate with a few small changes. I have a few more
features planned, but let's see how this goes first.
It's been an incredibly useful module in the past, I'm not sure right
now if I had ideas for potential improvements at some point, will need
to check notes.
What I'd really like, in addition to this, is a way to extract a query
from an $st object that can be run in the psql CLI. VNDB has a debugging
feature for that, but it's less trivial to make that work with binary
query parameters.
These macros don't assume alignment and may be somewhat inefficient with
all that copying. I'm hoping GCC is able to optimize that crap somewhat.
Also the pg type receive functions can not, in fact, assume that their
input buffers are properly aligned. That won't necessarily be the case
for array elements.
I liked the Perl implementation of transactions, but managing state
between Perl and C is a bit cumbersome, so I've moved the whole thing
into C.
Also added a few statement configuration methods that currently don't do
anything yet.
Partly because some errors currently appeared to come from within FU::PG
itself, which is useless, and partly because it's common to wrap
database access methods, while that's exactly the kind of operation
where you *really* want to know where the error originated from.
(Source: too much time wasted debugging VNDB errors)
It works and can format all "plain" Perl data, but has a few known bugs
and limitations that still need to be worked out.
It's about 8x smaller than JSON::XS's encoder and *much* smaller than
Cpanel::JSON::XS, but this is just a first attempt, it'll grow.
