Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.

Users of logical decoding can encounter unexpected change of
CurrentResourceOwner and CurrentMemoryContext. The problem is that in
reorderbuffer.c, unlike other call sites, we call
RollbackAndReleaseCurrentSubTransaction() without restoring the original
values of these global variables. This patch saves the values prior to the
call and restores them eventually.
