Hi,

I am running postgres 13 TDE and ran into the issue coder reporting the version is not v13 or higher.

After a bit of investigating I noticed coder uses "SHOW server_version".
Unfortunately the postgres TDE build reports it version other than a normal postgres build.
Postgres 13 TDE: "13.10_TDE_1.0.5 (Ubuntu.....)"
Postgres 12: "12.13 (Ubuntu...)"

In cli/server.go the version check splits at the space and proceeds to compare it with semver, which does not seem to like the additional content.

I addressed this by changing the server_version to server_version_num, as this is a number and the TDE information is not present. This also simplifies the comparison of the versions.
