If I run this query:
select sum(length(html)) from Indexer.Pages;
I get:
15,680,005,116
However, if I type:
C:\Program Files\PostgreSQL>dir /s
I get:
Total Files Listed:
5528 File(s) 7,414,385,333 bytes
575 Dir(s) 43,146,137,600 bytes free
So all the Postgres data on disk is a little over 7 gigs, however the
total sum of bytes in the HTML column of the Pages table is over 15
gigs.
Is PG compressing this data? I'm curious as I was considering
converting this column to a byte array and gzip'ing the data to save
space, however if PG is already doing this for me, then I'm not going
to bother. Thanks!
Mike
