NAME

+

my2pg - MySQL -> PostgreSQL dump conversion utility.

+

+

+

SYNTAX

+
+        mysqldump db | ./my2pg.pl [-nds] > pgsqldump.sql
+        vi libtypes.c
+        make
+        psql database < pgsqldump.txt
+where
+
+
pgsqldump.sql
+
+- file suitable for loading into PostgreSQL. +

+
libtypes.c
+
+- C source for emulated MySQL types (ENUM, SET) generated by my2pg +

+

+

+

OVERVIEW

+

my2pg utility attempts to convert MySQL database dump to Postgres's one. +my2pg performs such conversions:

+ +

It encloses dump in transaction block to prevent single errors +during data load.

+

+

+

COMMAND-LINE OPTIONS

+

My2pg takes the following command-line options:

+
+
-n
+
+Convert *CHAR DEFAULT '' NOT NULL types to *CHAR NULL. +Postgres can't load empty '' strings in NOT NULL fields. +

+
-d
+
+Add double quotes around table and column names +

+
-h
+
+Show usage banner. +

+
-s
+
+Do not attempt to convert data. Currently my2pg only tries to convert +date and time data. +

+
