Merge branch 'piggyback_master' into selection_handler
Merge branch 'piggyback_master' of https://github.com/mpws2013n1/postgres into selection_handler
unfished version of writing selection values to result struct
merge with piggyback master
write results of selection with a equation with a constant into the result structs; at the moment this will be overwritten by the old min/max implementation and the data could be stored for the wrong column
in case of selection with equality with a constant write min, max and most frequent value in the result struct
print correct min and max values in the client console
merge with prefinal stats
reordering in execMain for finding correct position for ExecInitNode (around line 980)
write selection values in the correct columnStatistics
merge with piggyback_master
calculate correct distinct values if they are not given by the selection
removed debugging print
fixed bug: compare table and column for identifing correct columnStatistics
added cast to int for console output
do not send and print statistics if the query result has 0 rows
extracted code for finding special selections
Merge branch 'selection_handler' of https://github.com/mpws2013n1/postgres into selection_handler
found opno for indexSeqScan
