Hi All,

We were getting the following error on executing a COPY command on postgres8.2.0.

SQL execution failed, Internal error. SQL Statement: (COPY command failed with error: ERROR:  row is too big: size 8200, maximum size 8136)

So, in order to fix the error we tried increasing the block size to 16k and recompiled the postgres library. The problem at hand was resolved with the new postgres library and we were now able to populate data for the mentioned query successfully. However, this experiment fails when we tried to run the new postgres on data directory generated with 8k block size which is likely to occur during an upgrade with postgres log showing the following error:

 

2008-12-30 14:57:33 IST  DETAIL:  The database cluster was initialized with BLCKSZ 8192, but the server was compiled with BLCKSZ 16384.

2008-12-30 14:57:33 IST  HINT:  It looks like you need to recompile or initdb.

 

What could be the possible solution to this?

 

 

Thanks,

Santosh.
