i want to install postgresql database and use from stackBuilder and postgis extension beacuse there are some issue in postgresql :
first : i want to download latest version of window setup.exe but redirect to access denied .
second :i find oldest version of setup file 9.3
PostgreSQL-9.3 reaches its End Of Life long way back so if you don't have any specific reason to use older/EOL version then please consider using the latest versions i.e PostgreSQL10 and onwards
