Fix 'Error: invalid sslmode value: "true"' in native mode

[sundbry]

When using PGSSLMODE env in native mode, an invalid database URL string
is constructed with sslmode=true/false.

Hey thanks for this! Is there a way to write a test for this? If not, if you could show an example in code that causes the problem I can write a test to exercise the fix. Either way I'm good - but need to get this under test so we don't regress on it! 😄

@Andrei-Stepanov There’s still no test. What configuration causes this error?

[Andrei-Stepanov]

@charmander : configuration/testcase scenario:

1. Have a postgresql-server without SSL transport.
2. Try to connect to this server using pg module enforcing/requiring SSL transport with env variable:
   PGSSLMODE=require.

Connection should not be established, but it is estalished. pg overrides this parameter.

@Andrei-Stepanov Which is it? Connection is established when it should not be, or Error: invalid sslmode value: "true"?

[Andrei-Stepanov]

I think this: Connection is established when it should not be.

@Andrei-Stepanov That sounds like an issue separate from what this PR claims to address (and what I was requesting a test case for), then. Please open an issue for it.
