rsync and symlinks

[tpmoney]

I have a postgresql installation that is using table spaces. As a result every table space exists as follows:

/pgdata/tablespace1
/pgdata/tablespace2

In addition, postgresql has a tablespace directory with symlinks that point to these tablespaces as follows:

/pgdata/pg_tblspc/27893 -> /pgdata/tablespace1
/pgdata/pg_tblspc/9802 -> /pgdata/tablespace2

I have a second machine that is going to act as a backup of sorts. Postgres can be backed up with rsync no problem, however, I don't want to rsync the entire /pgdata directory as it contains some machine specific information as well.

What I would like to do is be able to rsync the pg_tblspc directory, and have rsync copy the sym links and the linked directories to the remote machine, and create any /pgdata/tablespace* directories as needed, so that I don't have to worry about adding a new rsync command every time I create a new tablespace.

So instead of a script that does:
rsync /pgdata/tablespace1 ...
rsync /pgdata/tablespace2 ...
rsync /pgdata/pg_tblspc ...

I would just like to be able to run:

rsync /pgdata/pg_tblspc

I've been bouncing off this for a while and unfortunately, I can't seem to figure out the right combination of options that will both preserve the symlinks, and copy the linked directories and files to their appropriate locations.

EDIT:
---------

I tried doing an rsync --include="*/" --exclude="*" since what I'm concerned with copying are directories (and their contained files) but that appeared to only copy the directories and not the files within them.

I'd say rsync the symlinks first, then go back and get what they point to with something like this:

find -type l -print0 | xargs -0 readlink | xargs -I {} rsync {} destination

Will that also handle the creation of new table spaces without having to explicitly create the new table space in the destination? So for example:

BEFORE RSYNC AND FIND SCRIPT
source:
/pgdata/pg_tblspc/456 -> /pgdata/tablespace1/
/pgdata/pg_tblspc/4331 -> /pgdata/tablespace2/
/pgdata/pg_tblspc/6543 -> /pgdata/tablespace3/
/pgdata/tablespace1/
/pgdata/tablespace2/
/pgdata/tablespace3/

destination:
/pgdata/pg_tblspc/456 -> /pgdata/tablespace1/
/pgdata/pg_tblspc/4331 -> /pgdata/tablespace2/
/pgdata/tablespace1/
/pgdata/tablespace2/

AFTER RSYNC BEFORE FIND SCRIPT

destination:
/pgdata/pg_tblspc/456 -> /pgdata/tablespace1/
/pgdata/pg_tblspc/4331 -> /pgdata/tablespace2/
/pgdata/pg_tblspc/6543 -> /pgdata/tablespace3/
/pgdata/tablespace1/
/pgdata/tablespace2/

AFTER RSYNC AND FIND SCRIPT
  
destination:
/pgdata/pg_tblspc/456 -> /pgdata/tablespace1/
/pgdata/pg_tblspc/4331 -> /pgdata/tablespace2/
/pgdata/pg_tblspc/6543 -> /pgdata/tablespace3/
/pgdata/tablespace1/
/pgdata/tablespace2/
/pgdata/tablespace3/
