Ml/plt 5384 mintburn dbsync compare

[eyeinsky]

Status: figuring out redeemers is still in progress, but the rest passes the test.

PLT-5384: Main addition is this test here which:

• gets a random slot from an existing Marconi mintburn.db
• gets [TxMintRow] for that slot
• gets [TxMintRow] from a preexisting dbsync postgres database for that slot as well. (The sql query to get these from postgres is this one, confirmed correctness of this on cardano-db-sync's slack channel)
• compares them

Managed to find and fix a bug.

This test is meant to be run only manually as there are no pre-existing Marconi nor dbsync databases around in CI. Since the entire cabal component is set to "not buildable" with a flag. To build/run/repl it locally one needs to add --flag '-ci' to the cabal cli, so for example

• cabal build marconi-chain-index-test-compare-cardano-db-sync --flag '-ci'
• cabal repl marconi-chain-index-test-compare-cardano-db-sync --flag '-ci'
• cabal run marconi-chain-index-test-compare-cardano-db-sync --flag '-ci'

will work.

@koslambrou @berewt So it looks like I won't be able to finish this ticket.

The issue that remains is that redeemer hash and data don't always match between marconi and dbsync (if you set it to Nothing on both marconi and dbsync results then the test succeeds). The funny part being that they sometimes don't match. Might be worth it to double-check the sql query with dbsync team and also and maybe ledger or plutus-core team on whether the redeemer we save is correct.

There are TODO items in the test which help to see where it goes wrong.

How to run the test:

• sync mintburn indexer on preprod
• sync dbsync on preprod
• set env variables
• (run the test as described in issue description)
