Running the regression tests on mingw32, I get the following diff in circle.out:

This happens only with the 32-bit build (mingw32), but not with a 64-bit build (mingw64). Any suggestions on how to analyze this further? -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
