Issue getting TIMESTAMP and TIMESTAMPTZ columns from database

[cyclotron3k]

If Postgres returns a timestamp with microsecond precision (e.g. 2022-11-03 14:31:05.112156) or timezone information (1999-12-31 23:59:59+00) it causes the following lines in db-postgres-0.7.0/lib/db/postgres/native/types.rb:105 to blow up:

parts = string.split(/[\-\s:]/)
return Time.utc(*parts)

Note: Postgres will truncate trailing zeroes, so if you insert a timestamp with 0 milliseconds, Postgres will return a timestamp without a decimal point and this issue will not be triggered.

Full test case:

Sync do
	session = client.session

	session.clause("CREATE TABLE IF NOT EXISTS")
		.identifier(:users)
		.clause("(")
			.identifier(:a_timestamp).clause("TIMESTAMP NOT NULL")
		.clause(")")
		.call

	session.clause("INSERT INTO")
		.identifier(:users)
		.clause("VALUES (NOW())")
		.call

	result = session.clause("SELECT * FROM").identifier(:users).call

	puts "Result: #{result.to_a}"
	puts "Done"

rescue => e
	puts "#{e.class}: #{e.message}"
	puts e.backtrace
ensure
	session.close
end

Output:

ArgumentError: invalid value for Integer(): "05.112156"
