DBZ-8403 Fix PostgreSQL 17 compilation

When compiling against PG17 on Debian testing with gcc 14, building
fails because of incompatible-pointer-type error. This commit updates
the macros added in e1f8714 to handle the pointer types.

 If you have multiple Postgres versions installed, you can select which version to install decoderbufs into by altering your `$PATH` to point to the right version.
 Then `make` and `make install` for each version.  Here is an example:
 
-    # Install for Postgres 9.6 if I have multiple local versions
+```bash
-    export PATH=/usr/lib/postgresql/9.6/bin:$PATH
+# Install for Postgres 9.6 if I have multiple local versions
-    make
+export PATH=/usr/lib/postgresql/9.6/bin:$PATH
-    make install
+make
+make install
+```
 
 Once the extension has been installed you just need to enable it and logical replication in postgresql.conf:
 
-    # MODULES
+```bash
-    shared_preload_libraries = 'decoderbufs'
+# MODULES
+shared_preload_libraries = 'decoderbufs'
 
-    # REPLICATION
+# REPLICATION
-    wal_level = logical             # minimal, archive, hot_standby, or logical (change requires restart)

+max_replication_slots = 4       # max number of replication slots (change requires restart)
+```
 
 In addition, permissions will have to be added for the user that connects to the DB to be able to replicate. This can be modified in _pg\_hba.conf_ like so:
 
-    local   replication     <youruser>                          trust
+```make
-    host    replication     <youruser>  127.0.0.1/32            trust
+local   replication     <youruser>                          trust
-    host    replication     <youruser>  ::1/128                 trust
+host    replication     <youruser>  127.0.0.1/32            trust
+host    replication     <youruser>  ::1/128                 trust
+```
 
 And restart PostgreSQL.
 
 ## Usage
-    -- can use SQL for demo purposes
-    select * from pg_create_logical_replication_slot('decoderbufs_demo', 'decoderbufs');
 
-    -- DO SOME TABLE MODIFICATIONS (see below about UPDATE/DELETE)

+-- can use SQL for demo purposes

-    -- peek at WAL changes using decoderbufs debug mode for SQL console

-    select data from pg_logical_slot_peek_changes('decoderbufs_demo', NULL, NULL, 'debug-mode', '1');
-    -- get WAL changes using decoderbufs to update the WAL position
-    select data from pg_logical_slot_get_changes('decoderbufs_demo', NULL, NULL, 'debug-mode', '1');
 
-    -- check the WAL position of logical replicators
+-- peek at WAL changes using decoderbufs debug mode for SQL console
-    select * from pg_replication_slots where slot_type = 'logical';
+select data from pg_logical_slot_peek_changes('decoderbufs_demo', NULL, NULL, 'debug-mode', '1');
+-- get WAL changes using decoderbufs to update the WAL position

+
+-- check the WAL position of logical replicators
+select * from pg_replication_slots where slot_type = 'logical';
+```
 
 If you're performing an UPDATE/DELETE on your table and you don't see results for those operations from logical decoding, make sure you have set [REPLICA IDENTITY](http://www.postgresql.org/docs/9.4/static/sql-altertable.html#SQL-CREATETABLE-REPLICA-IDENTITY) appropriately for your use case.
