Max length of transactionId and eventId?

[Mr_Mannoroth]

1. Are there any length guarantees on the transactionId and eventId on Canton for PostGres?

2. We are integrating our Daml-based sytem with another system that uses RDBMS as permanent storage and needs the maximum length of a transactionId and eventId. What should be the max length to assume for these?

[Mr_Mannoroth]

Any ideas, anyone?
