X-Git-Tag: REL_18_BETA1~2355
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6a6ebb92b0d4c0787797538ec3ff342fd8e7c1ed;p=thirdparty%2Fpostgresql.git

Initialize wal_level in the initial checkpoint record.

As per Coverity and Tom Lane, commit 402b586d0 (back-patched to v17
as 2b5819e2b) forgot to initialize this new structure member in this
code path.
