The following bug has been logged online:
Bug reference: 3225
Logged by: Jens-Wolfhard Schicke
Email address: j(dot)schicke(at)asco(dot)de
PostgreSQL version: 8.2
Operating system: Linux
Description: BitmapOr plan node does not show currect row count
Details:
I an explain analyze I saw recently, a BitmapOr node of 5 Bitmap Index Scan
looked like this:
BitmapOr (cost=43.57..43.57 rows=1833 width=0) (actual time=0.146..0.146
rows=0 loops=1)
Yet, the last subnode was:
Bitmap Index Scan on location_gs (cost=0.00..8.14 rows=251 width=0) (actual
time=0.094..0.094 rows=375 loops=1)
The real rowcount of the BitmapOr is wrong.
