Hi, the use of :HOST in psql containing the socket directory for local connections is pretty useless for us, so we set it to the hostname in a global psqlrc file:
\set HOST `hostname -s` This works great when invoking psql on the command line. But if I perform a \c to connect to a different database in the database cluster, then :HOST gets reset to the socket directory. On the one hand, this makes sense, on the other, the global psqlrc file does not seem to be executed again, thus leaving :HOST in an unuable state for us: postgres=# \echo :HOST mypghost postgres=# create database test; CREATE DATABASE postgres=# \c test You are now connected to database "test" as user "postgres". test=# \echo :HOST /tmp The documentations (https://www.postgresql.org/docs/12/app-psql.html) says: "HOST The database server host you are currently connected to. This is set every time you connect to a database (including program start-up), but can be changed or unset." "Files psqlrc and ~/.psqlrc Unless it is passed an -X option, psql attempts to read and execute commands from the system-wide startup file (psqlrc) and then the user's personal startup file (~/.psqlrc), after connecting to the database but before accepting normal commands." Makes sense so far, except the last part "after connecting to the database but before accepting normal commands." This applies only to the first psql startup but not a subsequent \c. If I do a \c, then that is connecting to a database and that means, the psqlrc *should* be executed again, which it isn't. Bug or feature? If feature, is there any remedy to this behavior? Thanks in advance, Paul
