Subject: Remove redundant HandleWalWriterInterrupts().
X-Git-Tag: REL_17_BETA1~1021
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a044e61f1b97ceb80a198c0ae22c07c35dda39eb;p=thirdparty%2Fpostgresql.git

Remove redundant HandleWalWriterInterrupts().

Because of commit 1bdd54e662, the code of HandleWalWriterInterrupts()
became the same as HandleMainLoopInterrupts(). So this commit removes
HandleWalWriterInterrupts() and makes walwriter use
HandleMainLoopInterrupts() for improved code simplicity.
