Hi, i have a question, i have an case which on my table it has 14gb toast size while the data only consume 1.2Gb, and yes there are 2 Column storing a lot of text (payload) . I already perform vacuum and vacuum full on that table but the toast is still there. My question is
1. Is it normal having 14 gb toast size while the actual data onlly take 1.2 gb
2. If this aint normal, how to fix this?
Thank you!
