For a personal data analysis project, I was trying to find the most frequent 3 products that were being sold together by doing a self join (twice).
As the query was taking over 15 mins and the laptop fans seemed to be going into overdrive, I decided to stop it. This was all done through pgAdmin.
Upon checking immediately afterwards, I noticed that the size of my free space on the C drive decreased by 7GB (from the 15GB that it had been before).
Tried doing a VACUUM and a VACCUM FULL without any improvement.
Did some digging with WinDirStat and TreeSize and as far as I can tell, the file that changed during the time that the query was running was the pagefile.sys one.
Did the virtual memory somehow increase automatically? I am absolutely stumped by this. Thoughts?
One further thing I have tried was to clear the above mentioned pagefile.sys on computer shutdown but with no change in its size.
FWIW, this is the output for VACUUM FULL VERBOSE ANALYZE:
