>             Project: Hibernate Core
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.1.3
>         Environment: Hibernate 3.1.3, Java 1.5.0_07 (sun) windos and linux ( 32 & 64 bit). POstgres SQL 8.1 Windows and linux
>            Reporter: Alex Samad
>   Original Estimate: 1h
>  Remaining Estimate: 1h

> Whilst trying to insert into a table with a primary key (ID mapping) which has a identity generator. And the columns and/or the table has been defined with case sensitivey ie back ticks.
> It fails to get the next serial number and thus fails any inserts.
> The problem lies in dialect/PostgreSQLDialect.java
>         public String getIdentitySelectString(String table, String column, int type) {
>                 return new StringBuffer().append("select currval('")
>                         .append(table)
>                         .append('_')
>                         .append(column)
>                         .append("_seq')")
>                         .toString();
>         }
> table is inclosed in quotes and column is inclosed in quotes which gives a name like
> "table"_"Column"_seq - which fails
> I would suggest a fix is to test each of table or column for " and if it exist then to strip it of both of table and column and encluse the whole name in "".  This mighe break some old code where say the table is coded in case insensitive table name and case sensitive column key.
