While trying to test out the "EXPLAIN and nfiltered, take two" patch with its test file "explaintesti", I noticed I was getting a warning message like:
WARNING: problem in alloc set ExecutorState: detected write past chunk end in block 0x101134e00, chunk 0x101134f38 I got the same warning on unpatched git head as well. I was able to reproduce the problem with the attached input.sql file, along with a dummy input file, dummy_passwd, for the foreign table to read from. I get the above warning along with: ERROR: missing data for column "pass" CONTEXT: COPY passwd, line 1: "##" STATEMENT: SELECT * FROM passwd WHERE uid > 4; The error message is not surprising, since I am feeding the foreign table improperly-formatted lines. The warning is what concerns me; from the comments in aset.c and the warning message text itself, I gather this is not expected. I tested on OS X 10.6, with --enable-cassert --enable-debug. Josh
