But when I tried the same query on psql by replacing ($4) with a value like '20110404', the query works OK. The value of $4 is being passed from a java application. So does this mean I have to change the data type in java code?
By the way ,even log_statemtnts did not give me the bind variable value. It gave me values for bind variables for queries which got executed, not for this particular query. I am logging to csv file and loading it to the postgres_log as mentioned in the document. For this scenario, does the output go somewhere else? I am looking at the column query_text (select * from postgres_log where error_severity='ERROR' and log_time > '20110818')
and it shows .....AND ( CUSINDINF.MEMDOB )= ($4) ....
