Clear pgAdmin Cache on Mac
Clearing the pgAdmin cache frees some space and can fix odd behaviour when stale data is the cause. Your server list survives, because it lives in the pgadmin4.db file, which is not part of the cache.
Clear the pgAdmin cache without guessing
pgAdmin data usually takes 100 MB – 2 GB on a Mac. The free scan shows the exact size on your Mac before you change anything.

pgAdmin cache folders you can clear
pgAdmin has no separate cache folder. Its folders hold settings and your own data, so there is nothing to clear safely by hand.
What the pgAdmin cache holds
Specific to pgAdmin
The cache sits in ~/.pgadmin, the same folder that holds your own data. Inside it are sessions, storage and logs that pgAdmin rebuilds as it runs. Clearing helps when pages fail to load, the app behaves oddly after an update, or the folder has grown toward its typical 100 MB – 2 GB. The pgadmin4.db file, with your registered servers and settings, is not cache and stays where it is.
What happens after you clear pgAdmin's cache
The next time you open the app, it rebuilds the cache, so the first start will be slower than usual. Your servers and settings appear as before, because pgadmin4.db was left alone. You may be asked to sign in again, since session data was cleared. Your PostgreSQL databases are not affected, because the app never keeps them in this folder.
