PK indexes are different, because there can only be one pkey on a table,
there is no need for the 'field' part.
So your index name looks like <tablename>_pkey...
I guess, this answers your question about 'what table the error is
caused by'...
As for 'what SQL code', you can set debug_print_query=true in
postgresql.conf - this will make it print all the sql queries you
execute to the log file...
I hope, it helps...
