Ahh, About foreign key, it will solve by 08.03.0300. http://psqlodbc.projects.postgresql.org/release.html I think that it is solvable by 4.). It seems that I did what point of that mistake. We has forgotten the information of a release.....sorry. and, It seems that the test of UUID was not enough. http://cvs.pgfoundry.org/cgi-bin/cvsweb.cgi/psqlodbc/psqlodbc/convert.c.diff?r1=1.173&r2=1.174 One more condition fell out. http://archives.postgresql.org/pgsql-odbc/2008-10/msg00010.php Furthermore, I think it good to use libpq by which 8.3.5 was released. So, it is better to pack up 08.03.0310.? to Dave and Inoue-san. What do you think? Regards, Hiroshi Saito

Ok, agree. I will prepare it. Then, I need carefully packaging. ----- Original Message ----- From: "Dave Page" <dpage@pgadmin.org> > 2008/11/4 Hiroshi Saito <z-saito@guitar.ocn.ne.jp>: > >> Furthermore, I think it good to use libpq by which 8.3.5 was released. >> So, it is better to pack up 08.03.0310.? >> >> to Dave and Inoue-san. >> What do you think? > > 08.03.0400 sounds better to me. > > > -- > Dave Page > EnterpriseDB UK: http://www.enterprisedb.com > > -- > Sent via pgsql-odbc mailing list (pgsql-odbc@postgresql.org) > To make changes to your subscription: > http://www.postgresql.org/mailpref/pgsql-odbc

Hi, There are some chance to implement also correction for this bug: http://pgfoundry.org/tracker/index.php?func=detail&aid=1010303&group_id=1000125&atid=538 ? I attached a path for a change made on info.c of release 08.03.0300 source. I tested it with postgres 8.0 , 8.1 , 8.2 and 8.3 server and works fine. This is just a change on one query made by PGAPI_Columns function as showed bellow . . . (line 2066) /* * Create the query to find out the columns (Note: pre 6.3 did not * have the atttypmod field) */ op_string = gen_opestr(like_or_eq, conn); if (conn->schema_support) { strncpy(columns_query, "select n.nspname, c.relname, a.attname" ", case when t.typtype = 'd' then t.typbasetype else a.atttypid end as atttypid" ", coalesce(bt.typname, t.typname ) AS typname, a.attnum, a.attlen" ", case when t.typtype = 'd' then t.typtypmod else a.atttypmod end as atttypmod" ", a.attnotnull, c.relhasrules, c.relkind, c.oid, d.adsrc" " from (((pg_catalog.pg_class c inner join pg_catalog.pg_namespace n on n.oid = c.relnamespace", sizeof(columns_query)); if (search_by_ids) snprintf_add(columns_query, sizeof(columns_query), " and c.oid = %u", reloid); else { if (escTableName) snprintf_add(columns_query, sizeof(columns_query), " and c.relname %s'%s'", op_string, escTableName); schema_strcat1(columns_query, " and n.nspname %s'%.*s'", op_string, escSchemaName, SQL_NTS, szTableName, cbTableName, conn); } strcat(columns_query, ") inner join pg_catalog.pg_attribute a" " on (not a.attisdropped)"); if (0 == attnum && (NULL == escColumnName || like_or_eq != eqop)) strcat(columns_query, " and a.attnum > 0"); if (search_by_ids) { if (attnum != 0) snprintf_add(columns_query, sizeof(columns_query), " and a.attnum = %d", attnum); } else if (escColumnName) snprintf_add(columns_query, sizeof(columns_query), " and a.attname %s'%s'", op_string, escColumnName); strcat(columns_query, " and a.attrelid = c.oid)" " inner join pg_catalog.pg_type t on t.oid = a.atttypid)" " left outer join pg_attrdef d on a.atthasdef and d.adrelid = a.attrelid and d.adnum = a.attnum" " left outer join pg_type bt on t.typtype = 'd' and t.typbasetype = bt.oid" ); strcat(columns_query, " order by n.nspname, c.relname, attnum"); } I will be really happy if this can be fixed.

Hi Luiz-san. Sorry, very late reaction.... Release timing was being fixed. It seems that your proposal needs a complicated verification. I consider like an improvement rather than a bug. then, there are some worries. it is lo type etc.. However, It seems that Inoue-san review passes. but, it is next release. I appreciate your perseverance. thanks! Regards, Hiroshi Saito ----- Original Message ----- From: "Luiz K.
