2пёЏвѓЈ Modify pg_hba.conf to Temporarily Allow Login Without Password
Since restarting the service is costly, we will try to reload the configuration instead of restarting.
Step 1: Find pg_hba.conf
Run this in psql to find the configuration file location:
SHOW hba_file;
Open the file (likely in C:\Program Files\PostgreSQL\15\data\pg_hba.conf).
Step 2: Modify pg_hba.conf
Add this line at the top:
host all all 127.0.0.1/32 trust
This allows anyone on localhost to log in without a password.
Step 3: Reload PostgreSQL Without Restarting
Instead of restarting the service, reload the configuration:
psql -U any_existing_user -c "SELECT pg_reload_conf();"
This reloads the pg_hba.conf file without a service restart.
Step 4: Log in as sel_pgsql
Now, you should be able to log in without a password:
psql -U sel_pgsql -h localhost -p 5433
Step 5: Fix Permissions
Once logged in as sel_pgsql, restore your administrator privileges:
ALTER USER admin WITH SUPERUSER;
Step 6: Revert pg_hba.conf
Remove or comment (#) the trust line.
Reload the configuration again:
SELECT pg_reload_conf();
рџ”№ 3пёЏвѓЈ Use an Existing User With Privileges
From your \du output, these users can log in:
admin
diag
engineer
logger
readonly
sel_api
sel_pgsql (if you find the password)
sel_web
upgrade
If any of them can log in, use that account to elevate your privileges:
ALTER USER admin WITH SUPERUSER;
рџ”№ 4пёЏвѓЈ If You Absolutely Need to Restart PostgreSQL
If none of the above works, and you eventually need to restart PostgreSQL:
Find the running service:
net stop postgresql-x64-15
Restart it later when possible:
net start postgresql-x64-15
вњ… Expected Outcome
You should be able to log in as sel_pgsql without a password.
You can grant yourself superuser privileges.
No full restart needed—just a config reload.
