Here is a more comprehensive test: $ /usr/local/postgres-dev/bin/psql -x "\ host=server.uni-muenster.de hostaddr=172.19.42.1 user=jim dbname=postgres sslrootcert=server-certificates/server.crt sslcert=jim-certificates/jim.crt sslkey=jim-certificates/jim.key" psql (17devel) SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, compression: off) Type "help" for help. postgres=# SET ROLE foo; SET postgres=> \conninfo+ Current Connection Information -[ RECORD 1 ]------+--------------------------------------------------------------------------------------------------------------------------- Database | postgres Authenticated User | jim System User | cert:emailAddress=jim@uni-muenster.de,CN=jim,OU=WWU IT,O=Universitaet Muenster,L=Muenster,ST=Nordrhein-Westfalen,C=DE Current User | foo Session User | jim Backend PID | 278294 Server Address | 172.19.42.1 Server Port | 5432 Client Address | 192.168.178.27 Client Port | 54948 Socket Directory | Host | server.uni-muenster.de Encryption | SSL Protocol | TLSv1.3 Cipher | TLS_AES_256_GCM_SHA384 Compression | off postgres=> \conninfo You are connected to database "postgres" as user "jim" on host "server.uni-muenster.de" (address "127.0.0.1") at port "5432". SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, compression: off) A little odd is that "Server Address" of \conninfo+ differs from "address" of \conninfo... I think the documentation could add a little more info than just this: > When no + is specified, it simply prints a textual description of a few connection options. When + is given, more complete information is displayed as a table. Perhaps briefly mentioning the returned columns or simply listing them would be IMHO a nice addition. For some users the semantics of "Authenticated User", "System User", "Current User" and "Session User" can be a little confusing. And yes, I realize the current documentation of \conninfo is already a little vague :). Thanks for working on this -- Jim
