the problems is probably in my plugin :o)
however i dunno how to fully debug postgres activity
and i've understood why yesterday night :O/

the query i was using was something like:
select tableA.fieldA, tableA.fieldB from tableA where tableA.fieldA=8
the query report an error about >tableA<, but not WHERE/WITCH
tableA word reported the error.

it will be more <friendly> if the error was like

error in tableA:
select tableA.fieldA, tableA.fieldB from tableA where tableA.fieldA
like "tableA"
..............................^

or
error in tableA:
tableA.fieldB from tableA where tableA.fieldA=8

so it's simpler to understand what part of the query seems wrong

i've downloaded the jdbc source and debugged it, in the future
i will enable even this debug options however the problem was
about a prepared statement like
select tableA.fieldA, tableA.fieldB from tableA where tableA.fieldA like ?

while debugging it i thought it <processed> it while receiving, instead
it process it only after the parameter waz received and it has a full
query
select tableA.fieldA, tableA.fieldB from tableA where tableA.fieldA
like "tableA"
the <tableA> he doez not like if the first
select tableA.fieldA,
..........^

(the query i've used is only an example, the one i'm debuggins
is a little long and complex)

thanks :O)
