Architecture: Solaris 2.6 Sparc Compiler: gcc 2.95.1 postgres versionpostgres-v6.5.3 I am getting this no matter what value I pass to postmaster -B. There is something else going on here. I did have some problems with the compile but got the problems worked out. Any suggestions?

[ADMIN] Emergency questions for new bie
Hi, I'm an Oracle DBA, lately I began a project work on PostgreSQL 6.5.3 for Red Hat Linux 6.0. Every thing is fine, except: 1.How can I enable PG run as 'no-fsync' mode to improve performance? How can I check PG is in 'fsync' mode or not? 2. We have a table contain a column which use 'timestamp' data type. 'cause we need both date and time in this column, and don't want to break it into two columns with 'date' and 'time' data type(if so, we may have to change thousands of lines code, it origrinally works on Oracle). But when I tried to create an index on this 'timestamp' column, I got this error and creating failed: 'Cannot find a default operator class for type 1296.' I use this SQL command to create index: create index ind_name on tab_name(col_name); Can't I create index on 'timestamp' column? Right now since there's no index on this column, our app runs very very slow! THanks a lot! Jack

But when I tried to create an index on this 'timestamp' column, I got this error and creating failed: 'Cannot find a default operator class for type 1296.' Indexes don't work for timestamp in 6.5. Use datetime, or better yet upgrade to 7.0 which should be out in a few weeks. (jinx) -- Peter Eisentraut Sernanders väg 10:115 [EMAIL PROTECTED] 75262 Uppsala http://yi.org/peter-e/Sweden

[ADMIN] After creating user
Hello, I created new user, changed ownership of my database. But how can my user work with database if command 'psql' from UNIX can run only 'postgres' user? Thanks Mike __ Do You Yahoo!? Send online invitations with Yahoo! Invites. http://invites.yahoo.com
