[HACKERS] Timezones and time/timestamp values in FE/BE protocol
I'm working on a problem in the JDBC driver that's related to timezones. How does PostgreSQL handle timezones in the FE/BE protocol exactly? When a client sends a time or timestamp value to the server via the FE/BE protocol, should that be: 1) a value in the client's timezone? 2) a value in the server's timezone? 3) a value in a common frame of reference (GMT/UTC)? 4) any value with an explicit timezone? And how should a time or timestamp value returned by the server be interpreted in the client interface? And how does this all depend on the timezone setting of the server?

Re: [HACKERS] [JDBC] Troubles using German Umlauts with JDBC
[forwarding to pgsql-hackers and Bruce as Todo list maintainer, see comment below] [insert with JDBC converts Latin-1 umlaut to ?] On 04 Sep 2001 09:54:27 -0400, Dave Cramer wrote: You have to set the encoding when you make the connection. Properties props = new Properties(); props.put(user,user); props.put(password,password); props.put(charSet,encoding); Connection con = DriverManager.getConnection(url,props); where encoding is the proper encoding for your database For completeness, I quote the answer Barry Lind gave yesterday. [the driver] asks the server what character set is being used for the database. Unfortunatly the server only knows about character sets if multibyte support is compiled in. If the server is compiled without multibyte, then it always reports to the client that the character set is SQL_ASCII (where SQL_ASCII is 7bit ascii). Thus if you don't have multibyte enabled on the server you can't support 8bit characters through the jdbc driver, unless you specifically tell the connection what character set to use (i.e. override the default obtained from the server). This really is confusing and I think PostgreSQL should be able to support single byte encoding conversions without enabling multi-byte. To the very least there should be a --enable-encoding-conversion or something similar, even if it just enables the current multibyte support. Bruce, can this be put on the TODO list one way or the other? This problem has appeared 4 times in two months or so on the JDBC list.

[HACKERS] Multiple semicolon separated statements and autocommit
We're discussing an implementation of JDBC's Statement.executeBatch() on the pgsql-jdbc list. The idea is to send multiple semicolon separated statements in one call to the backend. The purpose of this feature is of course a performance improvement, since it executes multiple (non-select) statements with one round trip to the server. If autocommit is _enabled_ and S1;S2;S3 is send to the database, what exactly is the behaviour of the backend? For example, what happens if S1 succeeds, S2 fails and S3 would succeed? Does autocommit apply to the statement list send in one call as a whole? Or does it apply to individual statements? If autocommit applies to the list as a whole I assume the failure of S2 would cause the entire statement list to fail and be rolled back. If autocommit applies to individual statements in the list, I assume that S1 succeeds and is committed, S2 fails and is rolled back. But is S3 still executed? And what update count is returned to the client in that case? I will summarize on pgsql-jdbc.

How about an UPDATE statement that updates multiple rows? How about JDBC batchExecute() when it performs multiple INSERT/UPDATE's? ... Only the OID of the last UPDATE or INSERT statement in the batch? How about triggers that insert/update extra rows? ... Only the OID of the row directly inserted by the client statement? How about Large Objects? Should inserting or updating a large object affect getLastInsertedOID()? I assume this OID would be associated with a client connection. Is this going to work with client side connection pooling? How about transaction semantics? INSERT row 1, Commit, INSERT row 2, Rollback... what should getLastInsertedOID() return?
