Hi,
I have reviewed and tested the patch. Following are a few comments.
1.
The main objective of this patch is to get the dump which consists of SQLs
related to
CREATEDB only. I have tested the patch and it generates a proper dump file.
But my
concern is, it should execute the code which is necessary. But I see that
the code
is preparing some data which we may not dump. So I feel we should avoid
executing
such flows. Please correct me if I am wrong.

I agree with Cary that we should name this as 'createdb-only' and provide a
brief
description in help.
3.
if (!plainText)
dopt.outputCreateDB = 1;
+ if (dopt.outputCreateDBOnly)
+ dopt.outputCreateDB = 1;
+
'dopt.outputCreateDBOnly' if block can be merged with '!plainText' if block.
4.
static int binary_upgrade = 0;
static int column_inserts = 0;
+static int create_only = 0;
static int disable_dollar_quoting = 0;
The variable 'create_only' should be changed to 'createdb_only' to match
with
similar variable used in pg_dump.c.
Thanks and Regards,
Nitin Jadhav
