cf5894e092 Use std errors instead of golang.org/x/xerrors 
New error functionality was introduced in Go 1.13. pgconn only
officially supports 1.15+. Transitional xerrors package can now be
removed.

08d071c094 Handle IPv6 in connection URLs 
Previously IPv6 addresses were wrongly split and lead to a parse error.
This commit fixes the behavior.

84aee0ab44 Fix behavior of sslmode=require with sslrootcert present 
According to PostgreSQL documentation the behavior should be
the same as that of verify-ca sslmode

4ed48d05d2 Implement "verify-ca" SSL mode 
ParseConfig currently treats the libpq "verify-ca" SSL mode as
"verify-full". This is okay from a security standpoint because
"verify-full" performs certificate verification and hostname
verification, whereas "verify-ca" only performs certificate
verification.

The downside to this approach is that checking the hostname is
unnecessary when the server's certificate has been signed by a private
CA. It can also cause the SSL handshake to fail when connecting to an
instance by IP. For example, a Google Cloud SQL instance typically
doesn't have a hostname and uses its own private CA to sign its
server and client certs.

This change uses the tls.Config.VerifyPeerCertificate function to
perform certificate verification without checking the hostname when the
"verify-ca" SSL mode is set. This brings pgconn's behavior closer to
that of libpq.

See https://github.com/golang/go/issues/21971#issuecomment-332693931
and https://pkg.go.dev/crypto/tls?tab=doc#example-Config-VerifyPeerCertificate
for more details on how this is implemented.

99f22ac8e4 Port DSN parser from pgx v3 
Original implementation: 2d9d8dc52ac211c6191c08e050c03588aa633038 by
Joshua Barone <joshua.barone@gmail.com>.

Also changed DSN tests to use "dbname" as key rather than "database" as
that is what the PostgreSQL documentation specifies. "database" still
actually works but it should not be encouraged as it is non-standard.

3dec184811 Split ValidateConnect from AfterConnect 
This avoids the foot-gun of ParseConfig setting AfterConnect because of
target_session_attrs and the user inadvertently overriding it with an
AfterConnect designed to setup the connection.

Now target_session_attrs will be handled with ValidateConnect.
