When different users start PSQL Tool at the same time, the user who started it first will run psqlrc of the user who started it later.

When only UserA begins, UserA's psqlrc work.
UserA's $PSQLRC

db=> \! echo $PSQLRC
/var/lib/pgadmin/storage/usera_email.com/.psqlrc

But this case, other user's psqlrc had run.

UserA clicks PSQL Tool.

UserB clicks PSQL Tool before UserA's PSQL begins.

UserA's PSQL run UserB's psqlrc.

UserA's $PSQLRC

db=> \! echo $PSQLRC
/var/lib/pgadmin/storage/userb_email.com/.psqlrc
