Re: text search configuration missing while migration from 8.3 to 9.4

Oh thank you for answering me!!!

1) This is the 8.3 source:
select * from pg_ts_dict;
dictname | dictnamespace | dictowner | dicttemplate | dictinitoption

hwsplit_only | 21960 | 10 | 22342 | returnreplaced = 'false', keeporig = 'false'
(19 rows)

This is the target 9.4:
select * from pg_ts_dict;
dictname | dictnamespace | dictowner | dicttemplate | dictinitoption
-----------------+---------------+-----------+--------------+---------------------------------------------------

turkish_stem | 11 | 10 | 11592 | language = 'turkish', stopwords = 'turkish'
(16 rows)

As you see, last 3 records for dictnamespace 21960 are missing.

Another thing:
source (8.3):

\dF
List of text search configurations
Schema | Name | Description

pg_catalog | danish | configuration for danish language
pg_catalog | dutch | configuration for dutch language
pg_catalog | english | configuration for english language

pg_catalog | french | configuration for french language

pg_catalog | turkish | configuration for turkish language
public | hw_english | Hitwise configuration for the English language
(17 rows)

target (9.4):

\dF
List of text search configurations

------------+------------+---------------------------------------
pg_catalog | danish | configuration for danish language
pg_catalog | dutch | configuration for dutch language
pg_catalog | english | configuration for english language

pg_catalog | french | configuration for french language
pg_catalog | german | configuration for german language
pg_catalog | hungarian | configuration for hungarian language
pg_catalog | italian | configuration for italian language
pg_catalog | norwegian | configuration for norwegian language

pg_catalog | russian | configuration for russian language
pg_catalog | simple | simple configuration
pg_catalog | spanish | configuration for spanish language
pg_catalog | swedish | configuration for swedish language
pg_catalog | turkish | configuration for turkish language
(16 rows)

So, the last record "hw_english" does not show in the target.

This is the parameter in postgresql file, same on both locations.
# default configuration for text search
default_text_search_config = 'pg_catalog.english'

Unfortunately, I am not sure about tsearch2, it is new system that I inherited not too long ago. So, the production is still on 8.3, but dev/staging that was built recently, is on 9.4. The engineer who installed it said he used it from Puppet module for postgresql... He is not sure about tsearch2 module either. Do you know how can I find it? Or how can I install it? It seems like some gin indices are missing. I need to find out what is missing...

THANK YOU for your help

This is going to need some more info:

1) What records?

2) 8.3 was the version where text search was integrated into core. Where
you using tsearch2 before you moved to 8.3?

3) If the answer to 2) is yes, did you have the contrib/tsearch2 module
installed in 8.3 for backwards compatibility?

4) How was the 9.4 version installed?

4) If the answer to 3) is yes did you install the contrib/tsearch2 in
the 9.4 cluster?
