Re: Bug in tables column data in postgres database

Hello Team,
I don't understand why Java layer is involved here. If data is saved in
database table and with a select query wherever result will come that only
getting fetched from java layers as a result set.

If toggling behaviour is observed by me in tables column of postgres
database then how Java layer involvement comes.

At last my point of view is:
Here I have reported something that seems to a bug as I observe some
toggling behaviour . Just as a user only I have reported. And its all upto
postres db team to take it into consideration or not instead of pointing
out java layers.

Upto this much responses I got I didn't got satisfied reply.

Thankyou
