fix: sync command breakdown update and remove useless commands

 If the above command fails, you can diagnose and run the individual steps with the following commands:
 
+### 1. Syncing Sequences:
+
 - `sync-sequences` - reads and sets sequences values from SRC to DST at the time of command execution
-- `dump-tables` - dumps only tables without Primary Keys
+
+### 2. Syncing Tables without Primary Keys:
+
+- `dump-tables` - dumps only tables without Primary Keys (to ensure only tables without Primary Keys are dumped, DO NOT specify the `--tables` flag for this command)
 - `load-tables` - load into DST DB the tables from the `dump-tables` command (found on disk)
-- `dump-contraints` - dumps NOT VALID constraints from your SRC DB schema onto disk
-- `load-constraints` - load NOT VALID constraints from disk to your DST DB schema
+
+### 3. Syncing NOT VALID Constraints:
+
+- `dump-schema` - dumps schema from your SRC DB schema onto disk (the files may already be on disk, but run this command just to ensure they exist anyways)
+- `load-constraints` - load NOT VALID constraints from disk (obtained by the `dump-schema` command) to your DST DB schema
+
+### 4. Creating Indexes & Running ANALYZE:
+
+- `create-indexes` - Create indexes on the target database, and then runs ANALYZE as well.
+
+### 5. Validating Data:
+
 - `validate-data` - Check random 100 rows and last 100 rows of every table involved in the replication job, and ensure all match exactly.
-- `analyze` - Run ANALYZE on the database
