Thread: Tuple is too big ...

Hello all,

I am running PostgreSQL-7.0.3. I changed the value of BLCKSZ (in
"include/config.h" to 16384, recompiled and reinstalled the sources. After
having restarted the backend I tried to create a table with three
varchar(5000)-columns and tried to add three character-values with each 4000
characters.

The following error occurs:

  ERROR:  Tuple is too big: size 12044, max size 8140

What I am doing wrong? I would appreciate any ideas, because I urgently need
a solution ...

Best regards, Jens

Either you didn't do a full recompile (best to "make clean" then "make
all"), or you neglected to initdb, or some other procedural error.
