Re: proposal: schema variables

I did some testing locally. All runs smoothly, compiled without warning.

Later on (once merged) it would be nice to write down a documentation
page for the whole feature as a set next to documented individual
commands.
It took me a few moments to understand how this works.

I was looking how to create variable with non default value in one
command, but if I understand it correctly, that's not the purpose.
Variable lives in a schema with default value, but you can set it per
session via LET.

Thus "CREATE VARIABLE" statement should not be usually part of
"classic" queries, but it should be threatened more like TABLE or
other DDL statements.

On the other side LET is there to use the variable in "classic" queries.

Does that make sense? Feel free to ping me if any help with
documentation would be needed. I can try to prepare an initial
variables guide once I'll ensure I do understand this feature well.

PS: Now it is clear to me why it is called "schema variables", not
"session variables".
