You can backup and try using a different name, like:
hmpostgresuser
If that doesn't work, you will need to properly uninstall SQL and delete the postgresuser account.
For uninstalling SQL please follow these steps:
-Download Revo Uninstaller and use it to uninstall PostgreSQL. After it uninstalls it will give you options to select and delete all the associated registry entries. Do not do the final step which would remove the \data folder/files.
- manually delete the Program Files\Postgresql folders
- run the command - start > run > cmd >
PHP Code:
net user postgres /delete
- reboot.
- install again, with your firewall uninstalled or turned off if windows firewall
