Subject: Fix for change timeline field of IDENTIFY_SYSTEM to int8
X-Git-Tag: REL_16_BETA1~2362
X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=8ba3cb2f1863e3243aa40d73633bd88f774f74ce;p=postgresql.git

Fix for change timeline field of IDENTIFY_SYSTEM to int8

Amendment to ec40f3422412cfdc140b5d3f67db7fd2dac0f1e2: We also need to
change the way the datum is supplied to int8.  Otherwise, the value is
still cut off as an int4, and it will crash on 32-bit platforms.
