postgresql - Unaccent issue when restoring a Postgres database -

-

i want restore particular database under database name server well. far, good.

i used command :

pg_dump -u postgres -f c -o -b -f maindb.dump maindb

to dump main database on production server. use command :

 pg_restore --verbose -o -l -d restoredb maindb.dump

to restore database in database on our test server. restore ok, there errors, :

pg_restore: [archiver (db)] error while processing toc: pg_restore: [archiver (db)] error toc entry 3595; 1259 213452 index idx_clientnomclient maindbuser pg_restore: [archiver (db)] not execute query: error:  function unaccent(text) not exist line 1:  select unaccent(lower($1));                  ^ hint:  no function matches given name , argument types. might need add explicit type casts. query:   select unaccent(lower($1));  context:  sql function "cyunaccent" during inlining command was: create index idx_clientnomclient on client using btree (public.cyunaccent((lower((nomclient)::text))::character varying));

cyunaccent function in public shcema , gets created restore.

after restore, able re-create indexs perfecly same sql, without errors.

i've tried restore -i option of pg_restore single transaction, doesn't help.

what doing wrong ?

i found problem, , able narrow down simple test-case.

create schema intranet; create extension if not exists unaccent schema public; set search_path = public, pg_catalog; create function cyunaccent(character varying) returns character varying     language sql immutable     $_$ select unaccent(lower($1)); $_$; set search_path = intranet, pg_catalog; create table intranet.client (     codeclient character varying(10) not null,     noclient character varying(7),     nomclient character varying(200) collate pg_catalog."fr_ca"  ); alter table client add constraint client_pkey primary key (codeclient); create index idx_clientnomclient on client using btree (public.cyunaccent((lower((nomclient)::text))::character varying));

this test case pg_dump done in plain text.

as can see, cyunaccent function created in public shcema, it's later used other tables in other schema.

psql/pg_restore won't re-create index, cannot find function, despite fact shcema name specified reference it. problem lies in the

set search_path = intranet, pg_catalog;

call. changing to

set search_path = intranet, public, pg_catalog;

solves problem. i've submitted bug report postgres this, not yet in queue.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
