I get:
QUERY PLAN
------------------------------------------------------------------------
Result (cost=0.00..24.42 rows=8 width=48)
-> Append (cost=0.00..24.42 rows=8 width=48)
-> Seq Scan on data (cost=0.00..22.38 rows=5 width=48)
Filter: ((name)::text ~~ 'a%'::text)
-> Seq Scan on data_a data (cost=0.00..1.02 rows=2 width=23)
Filter: ((name)::text ~~ 'a%'::text)
-> Seq Scan on data_b data (cost=0.00..1.02 rows=1 width=23)
Filter: ((name)::text ~~ 'a%'::text)
(8 rows)
Both partition tables are scanned.
Best,

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
