Working from a mysqldump file

mysqldump writes a plain-text .sql file with a very consistent shape, which makes it one of the easiest dumps to read: its own syntax announces the dialect, and its rows are inline rather than in a separate archive.

  • Every mysqldump file contains ENGINE=InnoDB or AUTO_INCREMENT, which is exactly what the dialect detection looks for, so backtick-quoted identifiers and MySQL types parse without you choosing anything.
  • mysqldump packs many rows into one extended INSERT by default, and each tuple in it becomes a row, so there is no need to dump again with --skip-extended-insert.
  • The file is decoded as UTF-8 with unreadable bytes replaced, so a legacy latin1 dump arrives with damaged accented text. Dump with --default-character-set=utf8mb4, or run the file through iconv first.
  • mysqldump --tab is not a dump at all: the schema goes to a .sql file and the rows to headerless tab-separated .txt files. Neither half is convertible on its own, and the data files have no header row to name their columns, so dump again without --tab.

Loading into an application's database

PGSQL is the name PostgreSQL wears inside application code: PHP's pgsql extension, Laravel's pgsql connection driver, the pdo_pgsql DSN prefix. If that is where you met the name, the database you are loading into probably belongs to a framework, which changes what to watch for.

  • The script creates its own tables. Point it at a schema your migrations own and the next migration run and this file will disagree about who defines the table - load into an empty schema, or a database of its own, and point the application at that.
  • Because every identifier is double-quoted, the case the source used is the case that gets stored. A column that arrives as "CustomerID" has to be quoted in your queries too: an unquoted CustomerID folds to customerid and is not found.
  • No FOREIGN KEY, index or view statement is generated at all, so a framework that introspects the database finds unrelated tables. Declare the relations in your models, or add them with ALTER TABLE once the rows are in.

Reading mysqldump

  • Parsed with a real SQL parser, not regular expressions, so a value containing a closing parenthesis or a semicolon cannot split a row in half.
  • CREATE TABLE types, primary keys, NOT NULL and AUTO_INCREMENT are all read from the dump.
  • The source dialect is detected from the dump itself — MySQL, PostgreSQL and SQL Server dumps all parse.

Writing PGSQL

  • Backslashes are left alone, because PostgreSQL treats them as ordinary characters — doubling them would corrupt every Windows path.
  • Auto-increment columns become GENERATED BY DEFAULT AS IDENTITY.
  • Binary data is written as bytea, and identifiers respect the 63-character limit.

What you get

A ZIP containing dump.sql, plus a README with the exact command to load it. If anything about your data needed a judgement call, a _warnings.txt explains it.

Load this dump into PostgreSQL:

  psql -U USER -d DATABASE -f dump.sql

Create the database first if it does not exist:

  createdb -U USER DATABASE

Questions

Is converting mysqldump to PGSQL free?
Yes. Files up to 10MB convert free with no account. There is a limit of five conversions per day per IP address.
Will my mysqldump data keep its types in PGSQL?
Yes — that is the point. Whole numbers, decimals, dates and booleans are mapped to real PGSQL types rather than everything becoming text. The mapping table above shows exactly what you get.
Do you store my file?
No. The file is written to a temporary directory, converted, and the directory is deleted as soon as your download has been sent.
