I'm unsure if the documentation matches the code?
" connect_timeout #
<https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNECT-CONNECT-TIMEOUT>
Maximum time to wait while connecting, in seconds (write as a decimal
integer, e.g., 10). Zero, negative, or not specified means wait
indefinitely. The minimum allowed timeout is 2 seconds, therefore a value
of 1 is interpreted as 2. This timeout applies separately to each host name
or IP address. For example, if you specify two hosts and connect_timeout is
5, each host will time out if no connection is made within 5 seconds, so
the total time spent waiting for a connection might be up to 10 seconds.
"
The comments says that timeout = 0, means *Timeout is immediate (no
blocking)*
Does the word "indefinitely" mean infinite?
If yes, connect_timeout = -1, mean infinite?
