Description

Defined index names did not follow the recommended IX_ prefix convention across Oracle, SQL Server, and Postgres assets, and some Postgres test indexes retained redundant _idx suffixes.

Summary of changes

• Oracle: renamed config-related indexes to IX_* in bingo_config.sql.
• SQL Server: prefixed CONFIG, CONFIG_BIN, and CONTEXT indexes with IX_ in bingo_create.sql.
• Postgres: prefixed all test SQL index definitions/drops and regclass references with IX_, removed redundant _idx suffixes, and aligned related precache/metadata lookups.
• Test fixtures: adjusted example index to IX_compound to avoid redundant naming.

Example

-- Before
CREATE INDEX test_idx ON test_table USING gist (mol gist_bingo_ops);

-- After
CREATE INDEX IX_test ON test_table USING gist (mol gist_bingo_ops);
