Any of those help Use pg_dump to dump your current schema in a SQL-formated file. Open the file, replace the schemaname with the new name and excute this script in your database to create the new schema and all other objects inside this schema.

This might help you Fortunately, the structure of this schema is very predictable. You really just need to get comfortable with rep to be able to piece together what you need.
Here are all the pieces we need:
code :
Widths <- c(11, 4, 2, 4, rep(c(5, 1, 1, 1), times = 31))

Names <- c("ID", "YEAR", "MONTH", "ELEMENT", 
           paste0(c("VALUE", "MFLAG", "QFLAG", "SFLAG"), 
                  rep(1:31, each = 4)))

Classes <- c("character", "integer", "character", "character",
             rep(c("integer", "character", "character", "character"), 
                 times = 31))
out <- read.fwf(
    "ftp://ftp.ncdc.noaa.gov/pub/data/ghcn/daily/gsn/AQW00061705.dly",
    widths = Widths, header = FALSE, col.names = Names,  colClasses = Classes)
str(out[c(1:10, 120:128)])

Hope this helps It looks like the Novell LDIF reader is strictly accepting LDIF version 1 from RFC 2849. The first line should contain version: 1 OpenDJ does support adding schema over LDAP, it must be a change of cn=schema, adding values to the attributeTypes and objectClasses attributes.

To fix this issue Please keep in mind that using hbm2ddl.auto you can only update the structure of the database, not it's values.
For example: let's say you have

With these it helps I ran into this same issue. I found a solution after referencing this page: http://doctrine-dbal.readthedocs.org/en/latest/reference/types.html
Specifying the length of the text field will have the correct type created in MySQL. For example: length=65535
