Fix setvbuf()-induced crash in libpq_pipeline
Windows doesn't like setvbuf(..., _IOLBF) and crashes if you use it,which has been causing the libpq_pipeline failures all along ... and ourown port.h has known about it for a long time: it offers PG_IOLBF that'sdefined to _IONBF on that platform. Follow its advice.While at it, get rid of a bogus bitshift that used a constant of thewrong size. Decorate the constant as LL to fix. While at it, remove apointless addition that only confused matters.All as diagnosed by Tom Lane.Discussion:https://postgr.es/m/3458958.1617302154@sss.pgh.pa.us
