Обсуждение: varchar
Hi,
I would like to allow web site user to fill a field and for that i would need a large varchar()...maybe something around 100.000 characters.
i guess that VARCHAR can not hold so many character and that i should turn to bytea.
Am I right or is there some other possibility ?
i'm asking that because i've seen that bytea has some issues to store non ASCII characters like from UNICODE andSlovak language...
so how can i store central europe characters (UNICODE) into BYTEA field ?
thx,
Alain

Not at all -- PostgreSQL can fit roughly 1 gigabyte of data in a single varchar column. Avoid bytea for anything except purely binary data. Keep in mind that PostgreSQL is not able to index values longer than ~ 8 kilobytes. Note that the "text" data type, which is unlimited in length by definition, is usually preferred over varchar.
