How about moving LogicalRepWorkerType to logicalworker.h as in the
attached and then include that in pgstat.h? This requires few other
adjustments as previously some of the includes were working indirectly
via worker_internal.h.
Fixed few warnings via different includes after the above change:
*
procsignal.c: In function ‘ProcessProcSignalBarrier’:
procsignal.c:580:61: warning: implicit declaration of function
‘ProcessBarrierUpdateXLogLogicalInfo’
[-Wimplicit-function-declaration]
580 | processed =
ProcessBarrierUpdateXLogLogicalInfo();
|
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This warning appears because ProcessBarrierUpdateXLogLogicalInfo
declaration present in logicalctl.h was included in procsignal.c
through pgstat.h-
>worker_internal->walreceiver.h->xlog.h->logicalctl.h. Since the proposed patch
>removes worker_internal.h from pgstat.h this warning appears. For this, we
>need to include logicalctl.h in procsignal.c.
*
functioncmds.c: In function ‘compute_return_type’:
functioncmds.c:157:17: warning: implicit declaration of function
‘CommandCounterIncrement’ [-Wimplicit-function-declaration]
157 | CommandCounterIncrement();
This warning appears because CommandCounterIncrement declaration
present in xact.h was getting included in functioncmds.c through
pgstat.h->worker_internal.h->logicalrelation.h->logicalproto.h->xact.h.
to fix this, we need to include "access/xact.h" in functioncmds.c.

On Windows:
[68/196] Compiling C object
src/test/modules/test_custom_stats/test_custom_var_stats.dll.p/test_custom_var_stats.c.obj
../src/test/modules/test_custom_stats/test_custom_var_stats.c(685):
warning C4047: '=': 'HeapTuple' differs in levels of indirection from
'int'
Previously HeapTuple seems to be detected via
pgstat_internal.h->pgstat.h->worker_internal.h->logicalrelation.h->index.h->execnodes.h->tupconvert.h->htup.h.
To fix, we need to include htup_details.h in test_custom_var_stats.c
similar to test_custom_fixed_stats.c.
