How to set postgres server version?

[a137872798]

I start greptimeDB server and test jdbc.When i user prepareStatement, the response show Unsupported Server Version: 0.4.2. I find
the var associated with env CARGO_PKG_VERSION. I restart server with docker -e CARGO_PKG_VERSION=14.9 and found the env in container.But when I request again, the error still exist.

hi @a137872798 thanks for reporting the issue. May I know your JDBC driver version? Does it only happen when using prepared statement?

I think we will be hard-coding a fixed version that satisfies most client drivers.

My java postgres driver version is

and my postgres client version is 14.9.
By the way, are there any emergency measures to solve the problem.
