Take the logical OR of the values in register P1 and P2 and store the answer in register P3. If either P1 or P2 is nonzero (true) then the result is 1 (true) even if the other input is NULL. A NULL and false or two NULLs give a NULL output.
Take the logical AND of the values in registers P1 and P2 and write the result into register P3. If either P1 or P2 is 0 (false) then the result is 0 even if the other input is NULL. A NULL and true or two NULLs give a NULL output.
Relates to #127. This PR is still in draft and I have a few left things
to do (tests, improve implementation), just opening it so anyone can
track this work meanwhile.
Closes#664
This is a purely syntactic PR. It doesn't change behavior, just rewrites
some loops and removes unneeded parts, like lifetime annotations and
references. Mainly because the Clippy and IDE warnings get annoying.
Don't worry about the number of commits, I just separated based on type
of change.
Closes#732
I believe this closes#682

@PThorpe92 I don't think we need the `parent_op` machinery at all, we
just need to not jump to the `jump_target_when_true` label given by the
parent if we are evaluating the first condition of an AND.

Closes#698
This PR adds the `load_extension` function, and allows for platform
agnostic arguments: e.g. `select
load_extension('target/debug/liblimbo_uuid');` omitting the file
extension.
Closes#680
