[sunng87]

This patch brings next.jdbc/prepare to babshka-sql-pods

Thanks, I'll check if I can fix CI prior to merging this PR

[borkdude]

Can you merge with master?

[borkdude]

@sunng87 I think prepared statements should be saved in the pod side similar to connections.

Sorry for disturb I thought bb's sql api is same with next.jdbc but it's slightly different. I will find an environment to test my implementation locally later.

@sunng87 You can test it locally with a JVM version using this:

POD_DB_TYPE=...  script/test

Thank you @borkdude, after some experiments I realized this is a little more complex than my thought. Yes as you said we need to cache prepared statement because it cannot be serialized via transit. I will need some time to think about how to manage its lifecycle and provide unstandable api.
