Backend memory growing too much

Hi everyone,

I've been using sqlgrey for some time now and I'm very surprised by the
memory taken by the backends to which sqlgrey is connected.

look at process 4111 and 28108 . They roughly take twice the space the
other backend take.

Could there be a memory leak?

I don't know much about DBI/DBD but I know sqlgrey uses a lot of
prepare/prepare_cached statements.

What could cause?

shared_buffer is 400MB here.

TIA
