EDB Postgres Advanced Server 10

EDB Advanced Server is closely based on PostgreSQL 10.

EDB 10 also offers support for packages and synonyms. Packages and synonyms are supported in Change Script Generation, Reverse Engineering and in Reports.

Change Script Generation is based on PostgreSQL 10 and differences between EDB and Postgres might not be generated correctly.

Stored procedures

COST in stored procedures is rounded to 3 decimals during Reverse Engineering.

SET in stored procedures is loaded into AfterScript. Default value is 100.

By default procedures will execute with the privileges of the user that created them (SECURITY DEFINER). By default VOLATILE is set for procedures. By default procedures cannot be executed in parallel mode (PARALLEL UNSAFE). Default values are not generated in TDM.

User Data Types in the Model menu

Microsoft Access database does not have user data types. Nevertheless, these user data types in Toad Data Modeler  work only as an additional structure that can be used for a data type that Microsoft Access database supports but that is not available in Toad Data Modeler.

Generation of names in brackets

  • Check Delimited Identifiers in DDL Script Generation | Detail Settings to generate all names in brackets
  • If unchecked, names will be generated without brackets with exception of names that include spaces

Generation of captions

  • Check Generate Captions in DDL Script Generation | Detail Settings for MS Access models
