From b49013f2e86ad2cf01953f79992574e7ec2cdf02 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Fri, 13 Sep 2024 16:16:47 -0400 Subject: [PATCH] Allow _h_indexbuild() to be interrupted. When we are building a hash index that is large enough to need pre-sorting (larger than either maintenance_work_mem or NBuffers), the initial sorting phase is interruptible, but the insertion phase wasn't. Add the missing CHECK_FOR_INTERRUPTS(). Per bug #18616 from Alexander Lakhin. Back-patch to all supported branches.
