relayer basic

a basic relay implementation based on relayer.
uses postgres, which I think must be over version 12 since it uses generated columns.
it has some antispam limits, tries to delete old stuff so things don't get out of control, and some other small optimizations.

running

grab a binary from the releases page and run it with the environment variable POSTGRESQL_DATABASE set to some postgres url:

POSTGRESQL_DATABASE=postgres://name:pass@localhost:5432/dbname ./relayer-basic

it also accepts a HOST and a PORT environment variables.

if you know Go you already know this:

go install github.com/fiatjaf/relayer/basic

or something like that.
