bash-4.4$ ./pg_isready --version pg_isready (PostgreSQL) 14.2 bash-4.4$ ./pg_isready /var/run/postgresql:5432 - no attempt bash-4.4$ ./pg_isready -h localhost localhost:5432 - no attempt bash-4.4$ ./pg_isready -h localhost -p 5432 localhost:5432 - no attempt bash-4.4$ ./pg_isready -h localhost -p 5432 -d postgres localhost:5432 - no attempt bash-4.4$ ./pg_isready -h localhost -p 5432 -d postgres -U postgres localhost:5432 - accepting connections I always thought all parameters are optional? No? Thanks, Markus
