Postgresql is set to sslmode=require -> connection failed.

**Describe the bug**
void DbClientManager::addDbClient(const DbConfig &config)
{
if (std::holds_alternative(config))
{
#if USE_POSTGRESQL
auto &cfg = std::get(config);
auto connStr = buildConnStr(cfg.host,
cfg.port,
cfg.databaseName,
cfg.username,
cfg.password,
cfg.characterSet);

why we are using only host , port , databaseName, username etc only?
what if my postgresql set sslmode=require , then how to include sslmode etc into connection string

ConnectionString = "dbname=defaultdb user=avnadmin password={PASSWORD} host={HOST} port=22389 sslmode=require"
if sslmode=require on postgresql

**To Reproduce**

1. Go to aiven cloud (aiven.io)
