Bahram Jomehzadeh, I'd suggest you download the PostgreSQL installer from EnterpriseDB. Although the direct link to 9.2.2 is not shown on their downloads page, it's fairly obvious how to tweak the url to get to this older version. I installed it, then ran StackBuilder to install PostGIS 2.0.
Once you've installed it, you want to select, copy, and paste the following files from `C:\Program
Files\PostgreSQL\9.2\bin` to `C:\Program Files\ArcGIS\Desktop10.2\bin`: libeay32.dll, libintl.dll, libpq.dll,
ssleay32.dll, and libiconv-2.dll
Works for me™.
