Hallo ...
We have a problem with Gist fields when migrating from 7.1.3 to 7.3. Our
queries lead to different results. Actually data is lost somehow.
The problem occurs when running queries like that:
where (( key2img @ '{44756,44809}' or key2img && '{49582}' ) and not key2img
&& '{47343}' )
7.1.3 seems to return the correct result. 7.3 is much faster but returns
nothing.
Is it a bug? Is it a conceptual change? What went wrong? Did anybody
encount similour problems?
Regards,
Hans
