Operating Environment: Linux (3.13.0-62-generic, amd64) / UTF-8 / en / IN / Oracle Corporation 1.8.0_40-b26
Memory: Max=704,643,072;  Total=285,736,960;  Free=178,942,096;  CPUs=8

Steps to reproduce the issue :
1) Connect to PostgreSQL 9.3.6 or PostgreSQL 9.4.2.
2) Create a Table.

CREATE TABLE "public"."invoice"  (
    "invoice_no"      int4 NOT NULL,
    "seller_no"       int4 NULL,
    "invoice_date"    date NULL,
    "invoice_amt"     numeric(13,2) NULL,
    PRIMARY KEY("invoice_no")
)
GO

3) Create a Materialized View on above Table.
CREATE MATERIALIZED VIEW "public"."sales_summary"
    AS
    SELECT invoice.seller_no,
    invoice.invoice_date,
    (sum(invoice.invoice_amt))::numeric(13,2) AS sales_amt
   FROM invoice
  WHERE (invoice.invoice_date < ('now'::text)::date)
  GROUP BY invoice.seller_no, invoice.invoice_date
  ORDER BY invoice.seller_no, invoice.invoice_date
WITH DATA
GO

4) Now Right click on materialized View "Sales_summary" and Select 'Tools -> Object Search' option.
5) In Object Search Window, Select Database and Select Schema in which we have created above materialized view.
    From 'Object Types' section select "Materialized Views".
6) From 'Object Search' section, Select 'Object Names' and click on 'Search' Button.

Actual Result :
Existing Materialized views are displayed but materialized view icon is not displayed in front of them.
Also in 'Object Type' column 'MAT_VIEW' is displayed instead of 'MATERIALIZED VIEW'.

Expected Result :
Materialized view icon should be displayed in front of materialized views and  in 'Object Type' column 'MATERIALIZED VIEW' should be displayed.
