grant still broken

Well, I've rebuilt postgres again, using a fresh cvs snapshot, and grant is still broken. Infact, it gets worse. Once you try to use the grant statement, then any other connection that was active at that time - even on different databases, will die with the same message, hinting it may be something in shared memory that's breaking. Heres the output of psql, first as user postgres: [postgres@maidast pgsql]$ psql -h localhost db1 Welcome to the POSTGRESQL interactive sql monitor: Please read the file COPYRIGHT for copyright terms of POSTGRESQL type \? for help on slash commands type \q to quit type \g or terminate with semicolon to execute query You are currently connected to the database: db1 db1=> create table a (id int4,url text); CREATE db1=> insert into a values (1,'http://www.demon.co.uk/finder'); INSERT 18250 1 db1=> grant all on a to public; PQexec() -- Request was sent to backend, but backend closed the channel before responding. This probably means the backend terminated abnormally before or while processing the request. And as user pmount: [pmount@maidast pmount]$ psql -h localhost Welcome to the POSTGRESQL interactive sql monitor: Please read the file COPYRIGHT for copyright terms of POSTGRESQL type \? for help on slash commands type \q to quit type \g or terminate with semicolon to execute query You are currently connected to the database: pmount pmount=> create table a (id int4,url text); CREATE pmount=> insert into a values (1,'http://www.demon.co.uk/finder'); INSERT 18314 1 pmount=> select * from a; id|url --+----------------------------- 1|http://www.demon.co.uk/finder (1 row) pmount=> select * from a; PQexec() -- Request was sent to backend, but backend closed the channel before responding. This probably means the backend terminated abnormally before or while processing the request. NB: the select done as pmount was after the postgres user tried to grant rights, while the other statements were before. -- Peter T Mount petermount@earthling.net or pmount@maidast.demon.co.uk Main Homepage: http://www.demon.co.uk/finder Work Homepage: http://www.maidstone.gov.uk Work EMail: peter@maidstone.gov.uk -

Gee, still works fine here under bsd/os 3.0. #$ sql test Welcome to the POSTGRESQL interactive sql monitor: Please read the file COPYRIGHT for copyright terms of POSTGRESQL type \? for help on slash commands type \q to quit type \g or terminate with semicolon to execute query You are currently connected to the database: test test=> create table a (id int4,url text); CREATE test=> insert into a values (1,'http://www.demon.co.uk/finder'); INSERT 143530 1 test=> grant all on a to public; CHANGE test=> -- Bruce Momjian maillist@candle.pha.pa.us

It seems the others have no problems with BSD.

I am still running 6.2.0. Anything I need to watch out for when running the latest? -James

There was a reported problem with "group by" sorting which I could reproduce but which other platforms could not; it went away after a month or so. Maybe we'll get lucky on this one too :/ - Tom -

Just watch out for better performance :) Oh, there is a problem with varchar() at the moment.

I have a death in the family, so I'm not going to be able to sort it all out before this weekend. I get segfaults and authentication problems when trying to run perl scripts. Also, I'm not sure I have a handle on the new acl stuff. `Anyways', hopefully I can get everything worked out and compile a debug version to poke through with gdb this weekend. -James
