Please refer to http://www.devart.com/forums/viewtopic.php?t=21195. Is that what you mean (System.OutOfMemoryException on PgSqlDump.Restore())?

If not, please give us the following information:
1) the stack trace when the error occurs;
2) your current version (x.xx.xxx) of dotConnect for PostgreSQL. You can find it in the Tools > PostgreSQL > About menu of Visual Studio;
3) the steps we should follow to reproduce the issue:
a) your connection string (roughly, without credentials);
b) the version of your PostgreSQL server;
c) try to localize the issue by specifying the PgSqlDump.Schema and PgSqlDump.Tables properties. Which is table's content causing this problem? Please send us the DDL/DML script of this table.
