bigint,

index "planet_osm_line_pkey" btree (osm_id), Tablespace »planet3_is1

and there is no trigger on this table.

i wrote a pg/plsql function reading the table line by line using an 
exception condition and writing all records to a new table. program is 
running and some records have been ignored. it is quite easy to re-add 
the missing records - hope so.
