Naive build of interpreter hits missing symbol in libintrinsics

``` Crystal 1.3.1 [a6fcb1029] (2022-01-13) LLVM: 13.0.1 Default target: x86_64-unknown-linux-gnu ``` A naive `make interpreter=1`, `make install` (as root) of compiler version 1.3.1 from git yields this when I attempt...

Currently, one can only do COLLATE using the `.where()` operator, which is supposed to only be an escape hatch for handling the incompleteness of the current query set. The Postgres...

The developer should be guided away from direct use of Avram::DeleteOperation(T), rather than <Model>::DeleteOperation

3

In my naive reading of the documentation, I did not pick up that the developer should not use `Avram::DeleteOperation(T)` directly, and should instead use `::DeleteOperation`. This resulted in attributes and...
