Is it efficient to use Postgres as a column store by creating one
table per column?
I would query it with something like `[...] UNION SELECT value AS
<table> FROM <table> WHERE value = <value> UNION [...]` to build a row.
I'm thinking since Postgres stores tables in continuous blocks of 16MB
each (I think that's the default page size?) I would get efficient
reads and with parallel queries I could benefit from multiple cores.
Take a look at Zedstore, which is a column store built to plug into v12
storage layer:
