MySQL Stored Procedure to PostgreSQL Function Migration Guide

Read a partial procedure rewrite. The parameter list is rewritten by hand.

Updated 25 October 2026 · Migration Guide

This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.

What this hour is for

The converter removes a MySQL DELIMITER line and says a MySQL procedure becomes a PostgreSQL function or procedure. Rewrite the parameter list by hand. The rewrite is partial.

Do not run the sketch during the reading. Do not drop the MySQL source. Do not point the application at PostgreSQL until a copy has matching results for one procedure you named.

192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced. It is not a password you keep.

The change you can finish

Apply nothing while you are writing the note. When the lab window opens, it is one change on the database named in the ticket. Read the draft, then the database, then decide.

Rollback is the backup, the file, or the snapshot you saved first. You do not invent a rollback after the only copy is gone.

  1. Paste one procedure.
  2. Read the parameter note.
  3. Mark the parameter list as unfinished.
  4. Do not run the sketch.
  5. Stop.

Mistakes that outlive the statement

MySQL Stored Procedure to PostgreSQL Function Migration Guide goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.

Decisions to write down

One decision for MySQL Stored Procedure to PostgreSQL Function Migration Guide: The parameter list is marked unfinished. The source is still the source. Nothing was run. And the application was not switched.

Checks before you call it done

Confirm this before you call the change done: The procedure is named. Parameters are unfinished. The source is still the source. Nothing was run. And the application was not switched. If one of those fails, stop.

Before you leave the database

MySQL Stored Procedure to PostgreSQL Function Migration Guide ends when the database in the prompt is the database in the ticket. If it is not, you are on the wrong database. Stop.

The draft stays a draft until a person has read the names in it. A generator does not log into the database. You delete a line that names a host, a database, or an account you did not write down.

192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. They belong in the note. They are not values you leave on a database because a draft included them.

prompt-for-this is a reminder that a secret is missing. It is not a password, a key, or a token you save in the ticket or in git. A sample password in a draft is replaced. It is not a password you keep.

One change is the window. If two things move and the result is wrong, you will not know which one did it.

If the same step fails twice, stop for the day. Restore the copy you took first.

A second person reads the database name and the change aloud. If they cannot find them in the ticket, the note is not done.
