Yes, I know, but the backend does not allow for a bigger buffer. Trying
to use a 80K (char[81920])buffer did not work and returns:
INFO: string-size : 48015
INFO: +++++++++++++++++++++++++++
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Succeeded.
The surprising thing is that the data can be displayed using elog but
not returend with a string pointer.
You cannot just return pointer to stack (local for function) buffer - it gets freed on return from the function. You must explicitly palloc required memory chunk.
