@mawenge Thanks for you contribution. However, there are quite some test failures. Can you have a look?

@mawenge Thanks for you contribution. However, there are quite some test failures. Can you have a look?

I have fixed the tests, but after I rebase the main branch, there is a new error, and this seems not related to my change, can you please help take a look for this?

@mawenge The error should be fixed in main, maybe you need another rebase? Also, I assume the current default for connection pooling is disabled. We should not change the default for this value as this would be an incompatible change. Can you please let it default to false?
